Each beamsplitter reflects a standard laser line incident at 45° while efficiently passing the longer Raman-shifted wavelengths. The filters exhibit ultrasteep 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 for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.
