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

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

Display filters and films are designed to filter, enhanced 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

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

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

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

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

Optical flats or test plates are polished surfaces that are used as references against the flatness of unknown surfaces for comparison. They use the property of interference to measure the flatness of a test surface

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

Optical and optoelectronic design services assist with the initial conception and design of an optical or optoelectronic device or assembly

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

Hot mirrors and cold mirrors are dichroic filters that have a sharp transition between rejecting and transmitting at the near-infrared-visible area of the spectrum

Mirror mounts are used to hold and support mirrors of all sizes and shapes.
