Protect Lenses from Impurities

Protective filters protect lenses from dirt, dust, harsh ambient conditions and so on. Usually, they block a portion of the UV spectrum, although those used in infrared applications block visible wavelengths too.

Protective filters from Polytec come in glass or acrylic.

Mount & Size Options:

  • Threaded mount sizes: M22.5 to M105
  • C / CS mount, slip mount for lenses without filter threads, step-up / step-down adapter
  • Custom shapes and sizes; mounted and unmounted versions available
