Optical filters selectively transmit light in a specific range of wavelengths, while blocking the remaining colors. Esco offers three different types of filters, including Color Filter Glass, Neutral Density Filters, and Bandpass Filters.

All of these products are available through our optics catalog at standard size. If you need additional optical coatings, a different tolerance, or any other custom element, Esco has the technology to manufacture optics to meet your specifications.
