Dark-Sky Approved Devices

The Device Seal of Approval was created to recognise a wide range of technologies that help to reduce light pollution.

  • Obstacle Collision Avoidance System (OCAS inc.)
    The OCAS solution is an on demand obstruction warning system using advanced 3D radar technology and standard obstruction lighting. OCAS provides both visual and audible (optional) warnings to pilots on a potential unsafe heading towards the aviation obstacle (such as wind turbines, over head power lines, and towers). OCAS improves the environmental profile of these obstacles, by eliminating light pollution caused by unnecessary lighting.


  • Scallop Imaging
    Scallop Imaging provides businesses, individuals and the military with a range of high resolution camera technologies that dramatically improve visual capabilities without the assistance of artificial lighting or IR emitters.
