Where do I find infrared (IR) and ultraviolet (UV) transmission and reflection data for Celestron products?

We don’t have the data for regions outside the visible spectrum, since our products are marketed for amateur astronomy.

Please go to any Celestron Optical Tubes page, choose any scope and click on the link. When the page for that optical tube downloads, click on the Starbright XLT button at the bottom of the page for all the publicly available information on spectral characteristics of Celestron optics.

We suggest borrowing or buying one of our small Starbright XLT scopes from one of our dealers and testing it in your lab if you want to know what its characteristics are for non-visible parts of the spectrum.
