Simply best-in-class
 
 

OSRAM Opto Semiconductors’ innovative OSTAR®-Observation LED offers you the most powerful infrared LED array in the world. Designed specifically for CCTV applications and for use in night vision equipment, they deliver a wavelength specially adapted to CMOS/CCD camera systems. They are the optimum choice for covering long distances and monitoring extensive areas with infrared light, particularly in applications that require continuous operation and/or high ambient temperatures.

OSTAR®-Observation provides exceptionally low thermal resistance, is certified for automotive applications at temperatures up to 125 °C, and measures only 3.3x1.35 cm, yet emits IR light with a wavelength of 850 nm. With its compact, flat design, together with its high radiance, OSTAR®-Observation can be easily integrated in a variety of applications, including night vision and surveillance cameras, covert runway lighting, and perimeter security. In the automotive area, it can provide seat occupancy detection, driver monitoring and active night vision.
