Inrad-UV Filters

Crystalline optics are robust substrates from which optical filters of high purity and optical homogeneity can be fabricated.

In addition, optical elements, such as lenses, can be made from the substrates in order to provide both wavelength filtering as well as focusing.

In addition to the UV filters described here, proprietary filters are manufactured by Inrad for the defense community.
