Convex Hyperbolic Optical Elements

This service is not meant to supply amateurs with Cassegrain secondaries. It is primarily for scientific and military institutions looking for secondaries for long-wavelength high-energy scientific laser systems as a less expensive alternative to fabrication than using Hindle spheres or shells. Substrate material is fused silica and these secondaries can be made up to 12" in diameter. Secondaries are tested through the back using a unique  embodiment of the Schmadel test and can be very accurately made but the effectiveness of the unique methodology is only as good as the characterization of the primary and to a  degree the fabrication quality of the primary itself.

Please note that we are ITAR compliant and prefer customers that are US nationals such as universities and scientific institutions.
