2. About Thousand Oak's SolarLite Solar Film

Safely view the sun anytime and during all partial phases of an eclipse (a filter is required for all phases of an annular or partial eclipse). Thousand Oaks Optical's exclusive high quality SolarLite polymer substrates provide superior safety features, sharper solar images, and pleasing orange solar image. This solar eclipse film meet CE/ISO safety requirements. The transmission is 1/1,000th of 1% (Optical Density OD 5).

SolarLite: After years of R & D, Thousand Oaks has developed a new solar film that has the optical quality of the glass with the advantages of impregnated polymer (Thousand Oaks Optical Black Polymer). Images through this new SolarLite film are optically superior compared to the images from the older Thousand Oaks black polymer film. This new SolarLite film was released in very late 2016, so make sure that you get products with this newer SolarLite film.

This film will never develop pin holes or scratches that can let in light and ruin a filter. Other advantages: Light weight and does not require re-balancing tube assembly, will not break, consistent yellow-orange solar image, even density with any aperture, flat surface. Slight creases or wrinkles or warps may be present, but these will not have any impact on the solar image. Will not tear or puncture. Stronger than any other solar film on the market. Guaranteed 15 years.
