Mask Cutting Laser, Laserlith

We are pleased to announce the new Model 104 Mask Cutting Laser System. The first of these systems was installed at the Gemini North Telescope on Mt. Mauna Kea, HI.

February, 1999 Advanced Recording Technologies, Inc. designed, built, shipped, and installed a special version of the Laserlith, the Model 104, to the Gemini Dual Telescope Project in Hilo, Hawaii. This was the first "Mask Cutting Laser" accurate enough to be used by astronomers to study the red shift of stars and other celestial objects without interference from objects in the same region of space. The Laserlith has given astronomers a new and closer look at far distant stars, galaxies, and quasars.
