SolarLite Film Technology:
After years of research and development, Thousand Oaks Optical has introduced SolarLite—a new solar film that delivers the optical sharpness of glass with the durability and resilience of a polymer. Unlike traditional solar films, SolarLite won’t develop pinholes or surface scratches that could compromise safety. It’s lightweight, so it won’t require rebalancing your optical tube assembly, and it's built to withstand the rigors of field use.
SolarLite offers a consistent yellow-orange solar image across the entire aperture with excellent contrast and uniform density. Its smooth, flat surface ensures sharper views compared to other thin-film filters that often suffer from wrinkles and creases. Tear-resistant, puncture-proof, and more rugged than any other solar film available, SolarLite sets a new standard for safe, high-quality solar observing.
Safety Note:
Before each use, inspect your solar filter for any damage or defects. Never observe the Sun without a securely attached, undamaged filter in place.
