473 nm StopLine® notch laser dichroic beamsplitter

Semrock Part Number: NFD01-473-25x36

IDEX Part Number: FL-009316  /

Semrock
Each dichroic beamsplitter reflects a standard laser line incident at 45° while efficiently passing the shorter & longer wavelengths. This laser dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.
