Product Details

  • The Thousand Oaks Optical product line expands to include nebula filters created with the most current standard in multi-layer coating technology. Known as Ion Beam Sputtering, dielectric films of variable thickness can be applied in up to 200 layers to a single substrate, and the less complex design results in significant improvements in transmission and broad-spectrum blocking.

    The result? Brighter images and darker backgrounds on a filter far more resistant to environmental conditions. Thousand Oaks Nebulae Filters will include both Broad and Narrowband filters, Oxygen III (OIII), H-Beta and Minus Violet.
