Questar - A Case in Point

  The quality of our work? Astronomical!

The development and production of all of the optics that are used in the QUESTAR 3.5", 7", and 12" telescopes were accomplished by Cumberland Optical Company.
Questar's entire line of long distance microscopes, surveillance instruments, and custom lens designs is also produced exclusivey at our plant. All of these instruments use catadioptric systems with aspheric surfaces.
The Cumberland difference? Each and every instrument is hand corrected and perfectly matched to provide unparalleled images in clear, sharp, and accurate focus.
