IC optical and optoelectronic devices are chips designed for optical and optoelectronic applications

Optical manufacturing services design, fabricate, finish and test optical components and optical elements

Optical and light microscopes use the visible or near-visible portion of the electromagnetic spectrum to magnify images of objects

Optical materials consist of glasses, plastics, ceramics and coatings with reflectivity, opacity, color or other properties tailored for mirror, lens, laser or other optics applications

Optical comparators are instruments that project a magnified image or profile of a part onto a screen for comparison to a standard overlay profile or scale. 

Computer mouse and other pointing devices are used to control the screen-based movement of a cursor or icon on a visual computer. This category includes mice, trackballs, and touch pads

Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval.  Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation. 

Dry material (powders) level sensing devices are used to measure levels of solid, dry materials in either continuous or point values represented with various output options

Optical time of flight sensors determine displacement and distance by measuring the time it takes light to travel from the instrument to a target and back

Optical component accessories are used in the design or maintenance of optical components and systems

Optical time domain reflectometers (OTDR) measure the elapsed time and intensity of light reflected along an optical fiber. They are useful tools for locating problems in an optical network as they can compute the distance to breaks or attenuation

Optical and optoelectronic assembly services companies design assemblies and systems for optical and optoelectronic devices

Optical triangulation position sensors use reflected waves to pinpoint position and displacement

Wafer and thin film instrumentation includes quartz crystal microbalance (QCM) monitors, ellipsometers, RHEED systems, imaging stations, CD-SEMs, ion mills, and C-V systems specifically designed for wafer metrology or in-situ monitoring of thin film parameters during thin film or semiconductors wafer processing.

Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems
