## What We Manufacture

### Eclipse Glasses (EclipseGuard)
Certified solar eclipse glasses for public, institutional, retail, and promotional use.

### Sundara Optical Filters
Certified solar filters for cameras and telescopes using SCHOTT B270 optical glass (manufactured in Germany). Available in traditional threaded mount and MagniLock magnetic quick-detach format.
