Beam Splitters
 

Beam splitters allow a beam to be split into two beams of differing power, however, the most popular power split is 50:50 at a 45° incidence angle. The polarization needs to be considered when specifying a beam splitter otherwise the reflected and transmitted beams will not have the correct power. We have developed a special 'polarization insensitive' coating which eliminates this problem for the 50:50 case.

  • Advanced in-house design

  • Up to 500W/cm2 power handling

  • High quality laser grade material

The following standard beam splitter are available..
