The red LED point sources emit at a wavelength of 650 nm and are optimized for energy efficiency. Depending on the point diameter, visible emission of red light is reached with a driving current of 400 nA. This guarantees extremely long battery life in mobile devices such as reflex sights. The smallest point diameter we offer is 8 µm, which can be used to achieve coverage of just one minute of arc (1 MOA). As a result, this point source provides a perfect aim at even very distant objects. Thanks to the very short switching times, you can also use the LED point sources for data transmission.

Point sources with large point diameters are characterized by their high radiant intensity, making them ideal for use as light barriers. Point diameters of up to 150 µm are possible, depending on customer requirements.


  • High-precision: sharply defined and evenly illuminated reflection of the emission area.
  • Impressive performance: high radiant intensity with the aid of simple optics
  • Cost-saving: thanks to minimal power consumption, resulting in long battery life
  • Mobile use: compact design for applications with limited space
  • Individual: wide range of point diameters available; development of custom solutions also possible

Fields of Application

  • Electronics industry: substitution of VCSEL semiconductor lasers
  • Medical technology: for blood analysis, fluorescence microscopy and analytics
  • Security technology: as sights and light barriers
  • Metrology: distance measurement
  • Automation: beam barriers and rotary encoders
