Features
  • BK7 Optical Glass Dome

    The interior of the dome element is coated with a magnesium fluoride broadband anti-reflective coating to minimize internal reflections from camera lenses, lettering on cameras, etc. which can be problematic when shooting over/under scenes. The exterior is treated with a proprietary scratch resistant coating to control lens flare. This coating yields an amazing 99.7%+ transmissive value for true distortion free images.

  • Aluminum Shade

    The heavy duty shade is designed to offer lifetime service and extends far enough to protect the dome when placed face down.
