Filter Coating
Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, spectroscopy, clinical chemistry, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.

Reflective Neutral Density
Sheet
Reflective ND filters consist of thin film optical coatings, typically metallic, that have been applied to a glass substrate. The coating can be optimized for specific wavelength ranges such as UV-VIS or NIR. The thin film coating primarily reflects light back toward the source.
Bandpass filter layer
Bandpass filters are optical elements that are designed to transmit a specific spectral band with high efficiency, while reject others. The characteristics of the bandpass are controlled by multilayer dielectric coatings.
Laser Interference Coating
Laser line filters are narrow bandpass filters centered on the resonance of the laser, which attenuate the background plasma and secondary emissions that often result in erroneous signals.
