Red LED SharpDot™

greenfor printed circuit boardscustom

Product overview
Excelitas SharpDot point source and reticle LEDs use Resonant Cavity LED (RCLED) technology to produce sharp, well-defined dots and reticle patterns for red dot applications. The family delivers high electrical-to-optical efficiency for extended battery life and can operate at very low currents for night-vision compatible systems. A matte black encapsulation reduces stray light and reflections, improving pattern contrast. Multiple dot sizes, reticle geometries and color options are available, with standard and custom configurations supported by Excelitas.
