Description

Each beamsplitter reflects a standard incident laser line at 45° while efficiently transmitting the longer Raman-shifted wavelengths. The filters exhibit ultrathin transitions from reflection to transmission, with a guaranteed transition width of < 1% of the laser wavelength for the U-grade version. This laser dichroic beamsplitter is optimized to reflect laser beams up to 2.5 mm in diameter while minimizing RWE.
