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

Color filters include a wide range of filter types that are distinguished by their specific color spectrums and wavelengths, as well as their Schott glass compositions

Fiber optic filters allow only specific wavelengths to pass into a larger fiber optic system

Optical bandpass filters are designed to transmit a specific waveband.  They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light

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

Camera filters provide a range of optical filtering effects in scientific, research, and industrial applications

Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry

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

Spectral filters are used to selectively transmit light according to its wavelength. They are not to be mistaken with color filters, which can be differentiated by an associated schott glass number

Display filters and films are designed to filter and/or protect monitors or flat panel displays (FPD

Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation

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

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

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

Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength range
