Wasatch Photonics Announces Research Telescope Gratings

Logan , Utah , USA  - January 24, 2003

Wasatch Photonics, Inc., a leading designer and manufacturer of advanced holographic optics to the optical networking, defense, test & measurement, and medical industries, today announced a new line of volume phase holographic gratings for research telescopes.

Co-Founder and CTO Dr. Richard Rallison has over the past 25 years developed and refined high performance, volume phase holographic gratings using dichromated gelatin in his Ralcon Development Labs business.  Dr. Rallison said "I am glad to finally move my entire Ralcon telescope grating business into Wasatch Photonics where we are able to improve manufacturing quality, capabilities, and customer service."

Volume Phase Gratings are used in a new generation of telescope instrument packages to simplify spectrograph design and improve light collection efficiency.  "Diffraction efficiencies for Te (S) and for Tm (P) polarizations can be as high as 95% while diffracting through a 93 degree full angle (46.5 degrees half-angle) in the special case of a Dickson Grating" said Dr. Rallison.  The a-thermal gratings are sealed with glass on both sides resulting in a rugged, scratch resistant, easily handled product.
