Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. HR Optics has the largest selection of filters available from a single source, including Bandpass interference Filters, colored-glass filters, metallic and absorptive neutral-density Filters. Bandpass Interference Filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Colored glass Filters utilize the material’s inherent adsorption and transmission properties, while ND Filters evenly reduce transmission across a portion of the spectrum.

Mainly used in fluorescence microscopy, spectroscopy, clinical chemistry, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.
