Modern binoculars consist of two barrel chambers with an objective lens, eyepiece, and a pair of prisms inside. The prisms reflect and lengthen the light, while the objective lenses enhance and magnify images due to stereoscopic vision.
Man has been experimenting with glass since its advent sometime around 3500 B.C. These experiments soon became known for their ocular implications. The designs of early optical instruments, like the telescope, were not recorded. It is assumed that these instruments were studied and perfected by Galileo Galilei. Early binoculars were actually called binocular telescopes, and are thought to be based on Galileo's discoveries and designs of prisms.
Early telescopic lenses were full of bubbles and other imperfections. They were also slightly green due to the iron content in the glass. Polishing techniques were crude, and although lenses were of good quality in the center, the peripheral shape was poor resulting in a restricted aperture. As telescopes were improved, binoculars evolved. The first patent application for binocular telescopes was filed early in the seventeenth century by Jan Lippershey in present day Holland. Lippershey primarily used quartz crystal, which is hard to manipulate. The first hand-held binocular originated in 1702 with Johann Zahn's small binocular of two tubes with a lithe connection.
A patent application submitted in 1854 by Ignatio Porro began the use of the modern prism binocular called the Porro prism erecting system. This optical system consisted of an objective lens and ocular lens (eyepiece) with two facing, right angle prisms arranged to invert and correct the orientation of the image. The two most commonly used prism systems are the porro prism and the roof prism design. The roof system uses prisms positioned one over the other resulting in a more compact design.
An other major breakthrough occurred in 1894 when Carl Zeiss, a German optical specialist, developed binoculars with convex lenses and delta prisms to correct the inverted image. In a porro design, the light is bent in a "Z" shape before reaching the eye, allowing the distance between the eyepiece and the objective lens to be compacted. This enables the size and weight of binoculars to be reduced.
Reductions in the weight of the binoculars occurred with the use of aluminum or polycarbonate housings instead of the heavier metal alloys used in pre-civil war binoculars. Performance of smaller and larger binoculars has improved with the introduction of coatings to render the lenses non-reflective and reduce the amount of scattered light. The quality of prisms has also improved over the years, resulting in a reduction of the bubbling effect of optical glass. In the early 1970s, nitrogen filled, waterproof binoculars were developed. A decade later the arrival of infrared transmitters capable of seeing in the dark further transformed binocular technology. Variable magnification models were also developed allowing the user to adjust the level of magnification.
Raw Materials
Modern-day binocular tubes are primarily made out of aluminum coated with silicon or a leather-like material called gutta-percha. The lenses and prisms are made from glass and coated with an anti-reflective coating.
With the exception of the optical glass and some rubber seals, the majority of binocular component parts can be manufactured using a Computer Assisted Design and Manufacturing (CAD/CAM) system that downloads the designs to a variety of Computer Numerically Controlled (CNC) devices (multi-axis mill turn and milling machines as well as vertical and horizontal machining centers, lathes, etc.). Using CAD software provides both drawing, dimensioning, and visualization capabilities. These lead to improvements in the binoculars final design.
The Manufacturing Process
- The lens material is poured into a lens mold, which has a spherical curved bottom. This results in a lens that is about 4 in (10.2 cm) in diameter and 1-1.5 in (2.4-3.8 cm) thick.
- The lenses are then removed from the molds and cut into specific pieces using a diamond saw to create the optical lenses.
- The lenses are placed into the grinding machine and polished.
- After they have been carefully machined, the lenses are anodized to reduce reflections in vacuum tanks. The more coatings applied, the less light absorbed.
- The ocular lenses (nearest the eyes) are also molded and carefully polished by auto-polish machines after which they are centered on diamond turning machines and finally cleaned by running through several different solvents in automated machinery.
- The objective lenses, those furthest from the eyes, are molded and then polished with polishing machines.
- These components are then manually assembled into a die cast body, which is often made from aluminum.
- Using a technique called physical vapor deposition, the optics are placed into a "plasma machine" and coated with dielectric coatings. The coatings are essential for high performance.
- The optics are then inspected and tested for clarity and defects using lasers in specially designed particulate free rooms.
- Next, the rod shaped prisms are cut by lasers into three-sided shapes depending on the type of prism being manufactured (i.e., roof prisms or porro prisms).
- The prisms are coated with dielectric materials (metal oxides) by physical vapor deposition inside a vacuum chamber.
- When all these components are assembled on a belt assembly line, the final assembly station collimates the binocular by hand, making the left side exactly parallel to the right, so only one image will be seen at a time.
- The binocular housing is then covered with a substance called gutta-percha, which looks like leather but is more durable and flexible. This covering is applied by hand using an adhesive and may be coated with a protective rubber covering.
- On the assembly line bare metal housing covers are covered with plastic or rubber.
- The prisms are placed by hand inside the binocular casing and manually screwed in place.
- The objective lenses are held in place by a metal or plastic ring and the eyepiece is fitted with a rubber eyecap.
- The focusing lenses are placed in the housing with screws mounted by hand.
- Waterproof binoculars must have orings at every orifice, be purged with nitrogen (injected through a seal), and sealed. The final step would be the packing of binoculars in cases with neck straps, most cases today being of a canvas-like material.
Quality Control
Binoculars that have been hermetically sealed (waterproof) and nitrogen charged (fogproof) are tested underwater. Most binoculars will withstand water immersion at 16.4(5 m) for five minutes. Both barrels of a binocular need to be optically parallel for the image to merge into one perfect circle and are carefully checked for alignment.
Byproducts/Waste
Lenses and prisms that have defects such as scratches or cracks are either discarded and melted down to be molded again, or they are recycled. If the casing is damaged during production, it is also either remolded or recycled.
Binoculars continue to advance with new technology. Their ability to see further with better focusing techniques enables the consumer to use the product for a wider variety of tasks. Binoculars are now tending to use the same stabilizing method used in video cameras that automatically stabilizes the prism system so that the image remains steady to the viewer. Some binoculars are also coming equipped with night scope vision. This would enable the consumer to see objects that are far away even at night. Technological advancements are continually made on these specialty binoculars, which are primarily used by the military or for surveillance.

Presentation Transcript
Anatomy/Physiology of Binocular Vision • Goals • Follow the M and P pathway out of primary visual cortex • Answer where binocularly and disparity driven cells appear • Learn a bit about stereopsis • Answer (partially) how an oculocentric neuronal organization gives rise to an egocentric visual perception
Parallel Pathways: Magnocellular (M) and Parvocellular (P) • Each pathway is sensitive to specific visual stimuli • Each pathway has its own timing characteristics • Each pathway is NOT strictly parallel! • More of a “Bob ‘N Weave” pathway arrangement
Magnocellular (M-pathway) The Table Setter • Coarse visual form • Moving (or modulating)target • Processing time: rapid • Peripheral fusion • Coarse stereopsis
Parvocellular (P-pathway) The Details • Spatial detail • Chromatic detail • Stationary (or moving slowly) target • Processing time: slow • Fine stereopsis
Parallel Pathways On the Move • Lateral geniculate nucleus • Segregation of P and M pathways into layers (1-2 Magno.; 3-6 Parvo.) • LGN serves as a relay station to primary visual cortex (18) • Where vision will become a conscious event • Where stereopsis and fusion takes place • Where visual and cognitive processing take place
Primary Visual Cortex (V1) • Located along calcarine sulcus • M and P pathways continue in different paths as they reach layer 4 of V1 • M pathway to layer 4 Ca • P pathway to layer 4Cb and layer 4A • Organized into ocular dominance zones • Monocular cells in layer 4C • Binocular driven cells outside of layer 4C
Parallel Pathways in V1 • M pathway: • From 4Ca to layer 4B in same vertical column (1 mm wide) • From 4B to layers 2/3 in same vertical column (1 mm wide)and neighboring columns
Parallel Pathways in V1 • P pathway: • From 4Cb to layers 4A and 3 in same vertical column (1 mm wide) • In layer 3, cytochrome oxidase, a metabolic marker, has dense staining in layer 2/3; absent in layer 4 • Called “blobs” • Although considered “P-cells only”, a significant M-pathway input exists
Parallel Pathways in V1 • Blob and interblob regions:a split in the parvocellular pathway • Blob regions are situated in the center of ocular dominance columns • Blob regions: color opponency, low contrast and spatial frequency, not orientation selective • Interblob regions: little color opponency, high contrast and spatial frequency, very orientation selective
M and P Pathways In V2 • V2 has areas of high cytochrome oxidase activity in form of thick and thin stripes • M pathways project to thick stripes • P pathway • Blob cells: thin stripes • Interblob cells: inter stripes
Other Visual Areas • V2: in area 18, flanking V1 • Thin/inter stripe regions (P pathway) projects to V4 • Thick stripe (M pathway) projects to V3 and MT • Some overlap in response characteristics in V2 due to “cross-talk” between M and P at blob region
Other Visual Areas • V3: in area 18 flanking V2 • Receives M pathway input • Output to middle temporal area (MT) • Also output to V4!?! • V4 • Receives P-pathway input from thin/inter stripe regions of V2 • Receives strong M-input
Vision Association Areas • Area MT • In parietal lobe • M-pathway input • Output to parietal areas and V4 • Sensitive to motion • Some areas have receptive fields in head-centric coordinates, NOT oculocentric
Vision Association Areas • Posterior parietal cortex • M-input (MT/V4): coarse stereopsis, low spatial freq., fast flicker and motion • Spatial position and object motion • Inferotemporal cortex • P-input (V4): fine stereopsis, color vision, fine pattern vision • Complex object recognition: faces
Final Words About M/P Pathways • Significant cross-talk in V1, V4 and beyond • Ultimately, these two independent, yet overlapping streams must converge to form unitary perceptions of objects • We do not process the world like a poorly printed photograph, with the colors offset
Ocular Dominance Columns • Vertical columns that respond most strongly to one eye • Extends through the full thickness of V1 • Absent in areas outside V1 • Binocular cells outside layer 4C respond predominantly to one eye over the other
Orientation Columns • If ocular dominance columns are loaves of bread, orientation selective columns are slices (parallel to pia) • Orientation selectivity is interrupted by blobs
Binocular Cells and Stereopsis • Binocular cells in V1 receptive fields for each eye share most characteristics • Corresponding retinal loci • Latency • Size/shape of receptive field
If perfect overlap of receptive fields exist, it argues for a creation of an EGOCENTRIC PERCEPTION early in visual processing It cannot explain, however, why we are sensitive to binocular disparity (stereopsis) Binocular Cells and Stereopsis • Binocular cells in V1 receptive fields for each eye share most characteristics • Corresponding retinal loci • Latency • Size/shape of receptive field
Results from different perspective of each eye to a particular visual target Neurons tuned to disparity have been found in V1 Receptive fields for each eye do not PERFECTLY overlap More prevalent in V2 (75% cells tuned to disparity) 4 main classifications of disparity tuned cells Near cells/ Far cells Excitatory cells tuned to zero disparity Tuned excitatory Tuned inhibitory Binocular Disparity
Profiles of Disparity Tuned Cells • Near cells: resp. to targets closer than fixation distance • Far cells: resp. to targets farther than fixation distance • Excitatory cells tuned to zero disparity: narrow peak responses around zero disparity
Profiles of Disparity Tuned Cells • Tuned excitatory: stim. by stimuli near zero disparity BUT ON EITHER SIDE/ suppressed by uncorrelated images • Tuned inhibitory: suppressed by stimuli near zero disparity BUT ON EITHER SIDE / stim. by uncorrelated images

binoculars , optical instrument, usually handheld, for providing a magnified stereoscopic view of distant objects. It consists of two similar telescopes , one for each eye, mounted on a single frame. A single thumbwheel may control the focus of both telescopes simultaneously, and provision may be made for adjusting the focus of each separately to allow for varying characteristics in the two eyes. Binoculars are designed to give an upright view that is correctly oriented left-to-right. Because they allow use of both eyes in a natural way, they are more comfortable than single telescopes, provide depth perception, and improve visual acuity by giving the human visual system two sets of data to process and combine.
In most binoculars, each telescope is provided with two reflecting prisms . The prisms reinvert, or erect, the inverted image supplied by the objective of each telescope. They prescribe a folded path for the light rays, allowing a shorter overall length for the instrument. When the prisms used are of the Porro type ( see optics: Reflecting prisms ), they also provide better depth perception at greater distances by allowing the two objectives to be set farther apart than the eyepieces. The arrangement of these prisms and the other optical components is shown in the illustration .
The primary optical characteristics of a pair of binoculars are commonly described by two numbers, the first of which is followed by a multiplication sign—for instance, 7×50. The first number indicates the magnification (e.g., 7×, meaning “7 times”) and the second the diameter of the objective in millimetres (1 inch is about 25 millimetres). This latter figure is a measure of the light-gathering power of the instrument. For a given magnification, larger objectives produce a brighter image in dim light but also create a more massive pair of binoculars. Handheld binoculars designed for typical uses such as hunting, sports watching, nature study, or amateur astronomy range from about 6×30 to 10×50. Instruments having greater magnifications and light-gathering power are too heavy to hold steady, especially for long periods, but they can be fixed to a tripod or other mount.
In applications in which depth perception is not important, a single telescope, called a monocular, may be employed. It is essentially one-half of a pair of binoculars and usually incorporates prisms in the light path.
Opera glasses and field glasses are binoculars with simple, often inexpensive lens systems and narrow fields of view and are usually made with magnifications of 2.5× to 5×. The lenses used in most binoculars are coated on some or all of their air-to-glass surfaces to reduce reflections.
