- The RL3940 is available in a wide range of wavelengths from UV to IR.
- The folded-beam configuration provides dark field illumination in a compact 3.9” (100mm) housing.
- The housing’s large inner diameter can accommodate lenses up to 55mm in diameter.
- The light can also be ordered with an optional mounting ring.


Acquire high quality images with accurate radiometry for LEO (Low Earth Observation) earth observation applications with 65 MP focal plane and control electronics. From a 500 km orbit, SEEING™ 230 Ident has 9 x 6 km2 swath, offering a 1.03m native Ground Sample Distance (GSD), and features a super-resolution optional mode providing 70cm GSD. Thanks to its unique design, SEEING™ 230 Ident has an ultra-low SWaP factor. It is made of advanced ceramic material for strength during launch and stability during operation in space. It is athermalized and gradient insensitive between -10°C to +50°C. It has a low mass, below 8kg, saving both platform and launch costs.
- Our EuroBrite™ lineup outdoes the competition in so many ways. With more features at a competitive price point, there’s no better value in machine vision lighting:
