Full Spectrum in Precision Optics: Lenses, Test Plates, Prisms, Mirrors, Optical Systems, Beamsplitters, Aspheric Optics, and more.

Capabilities Include:

HEAVY-DUTY Generators with specially designed diamond wheels accomplish the preliminary shaping in a minimal amount of time.

They are used to: 
  • Drill
  • Generate curves
  • Grind flats
  • Edge diameters
  • Bevel and chamfer safety corners
HIGH TOLERANCE Testing, which goes beyond the capabilities of an electronic spherometer, is accomplished by using test plates, Rhonchi testing, and autocollimating. Our ZYGO Interferometer provides the highest level of accuracy testing, with computerized data read-outs.

MASTER TEST PLATES are made for every curve to insure that elements in production are precisely the same as the original. Test plates are also available, flat or curved to your specifications. A WIDE VARIETY OF COATINGS, both reflective and antireflective are available, using our in-house high vacuum-coating facilities.

Optical elements can be coated with any of these materials: Magnesium Fluoride, Chromium, Aluminum, Gold, Silicon Monoxide.

Complete multilayer coatings are also available upon request.
