Neutral density filters are designed to reduce transmission evenly across a portion of the spectrum. They are slightly sensitive to angles but they are much more forgiving than interference filters

Densitometers measure the optical, photographic or area density of a material. They are used in a wide range of applications, from film processing to medical scans

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 windows are used to isolate different physical environments while allowing light to pass relatively unimpeded

Opacity sensors and instruments measure the amount of light transmitted through a sample.

Optical apertures and slits control the diameter of beams from light sources

Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources.

Optical mounts are specialized holders designed for use with a variety of optical assemblies

Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device.

Optical diffusers scatter incident light, thereby reducing the sensitivity of a detection system to slight positional or angle changes in an incoming beam

Optical tables and breadboards effectively dampen working surfaces with superior flatness. They are used in the precision mounting of optical components

Optical interconnects are flexible jumpers used to interface or connect with integrated circuits (ICs), or circuits in general

Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.

Optical calibration standards are used to calibrate the optical properties of optical detectors and instruments

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors
