Precision Mirrors

©️ Private

Custom high-reflectivity optical mirrors deliver superior performance and value when designing and building laser cavities from small, lightweight rangefinding lasers to high laser damage threshold industrial lasers.

We design and manufacture our precision mirrors, by hand, in both the United States and the United Kingdom.

Eliminating defects

The smallest defect on an optical surface often leads to system failure. Our goal is to minimize or eliminate system failures by offering the highest quality polishing and coating for our precision optical mirrors.

Precision mirrors are fabricated in a number of shapes and sizes, including aspheric and off-axis. Conventional optical grade flats or shaped substrates are precision polished and inspected at magnification and using white light interferometry to ensure there are no underlying defects before coatings. Careful cleaning and coating processes ensure microscopic particles are not encapsulated into the coating.

Durable and dependable

Dielectric laser cavity and beam routing mirrors demonstrate very high reflectivity and high laser damage threshold.

Protected and enhanced metal reflector coatings offer superior abrasion and climatic resistance for lower power applications.
