427 nm edge LaserMUX™ single-edge laser dichroic beamsplitter

Semrock Logo

LaserMUX filters are designed to efficiently multiplex or demultiplex (combine or separate) laser beams at a 45° angle of incidence. These ultralow-autofluorescence filters are ideally suited for multi-laser fluorescence imaging and measurement applications such as laser microscopy and flow cytometry. This laser dichroic beamsplitter is optimized for reflecting laser beams up to 2.5 mm in diameter while minimizing RWE.
