55mW Lasers

What are 55mW Lasers?

Lasers that designate 55mW (0.055W) of output power can have either CW (continuous wave) or pulsed output. CW Lasers are always defined in average output power. Pulsed Lasers with an output power defined in Watts or Milliwatts usually define the laser’s average power, not the peak power of the laser.

Our 55mW Laser Products

For example, RPMC has a 55mW, single emitter, single-mode laser diode, emitting at 685nm, in a 5.6mm TO-can package, perfect for machine vision, optogenetics, and as an RGB light source.
