633 nm StopLine® notch laser dichroic beamsplitter

Semrock Logo

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.

Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spectral plot data, please see here for more information.
