LRD Lasers

Line lasers

Our LRD series lasers are maybe the most powerful diode based lasers on the market. Latronix has installed several thousands of LD- and LRD-lasers in sawmills and other heavy industries.

With our high output powers the LRD-Lasers produces lines with a much better brightness than He-Ne lasers normally do. There is no high voltage inside. In addition they are more compact and rugged and have a longer lifetime.

LRD laser
  • Diode laser system with long lifetime
  • Robust design
  • Compact Heavy-duty encapsulation
  • High visibility even in intense ambient light
  • Sharp and narrow lines even at long distances
  • Red or green light
  • CE-mark
Red light ...

The output power ranges from 6mW up to a current maximum of 125mW when using 635nm diodes. The reason for choosing 635nm as a standard wavelength is that this has the best visibility for the human eye amongst the red colours.

... but also green LRD

In the green light LRD-lasers source is a diode pumped YLF-laser with frequency doubling. The green light is located close to the maximum sensitivity of the human eye and the laser line has a far better visibility than red light with the same output power. Compared to a 635nm light the visibility is 4 - 5 times better, so an 6mW green laser gives the same brightness as a 24 - 30mW red laser with a wavelength of 635nm.
