Laser Application Filters

Laser Mirror Transmission Curve

Dontech, Inc. manufactures laser blocking filters and optical assemblies for military, medical, and commercial applications.

Military periscopes and viewing systems used on land or amphibious vehicles require laser blocking filters to prevent eye injury to operators from enemy laser fire. Dontech’s laser blocking filters utilize proprietary multi-layer, dielectric coatings to separate infrared radiation from the visible part of the spectrum. Dontech laser blocking filters are designed to meet the stringent optical performance, environmental, and coating durability requirements.

For medical and commercial lasers, Dontech manufactures narrow band pass and long pass filters for transmission of laser radiation such as bar code scanners, surgical lasers, and laser sensors. Please contact a Dontech applications engineer for additional information.
