Dichroic Laser Beam Combiner, 25mm, 633-647nm Reflect, 671-790nm Trans

The DCM15 Dichroic Laser Beam Combiner is a 0.98 inch (25.0 mm) diameter long pass edge filter with high reflection (> 98%) at 633-647 nm, and high transmission (> 95%) at 671-790 nm to efficiently combine or separate multiple laser beams at 45° angle of incidence. Made from low autofluoresence substrate with dense ultra-durable coatings, it is an ideal choice for applications involving multi-laser Fluorescence Microscopy, combining or splitting two beams of different wavelengths, spectral components filtering, and any laser applications requires minimal wavefront distortion. These Beam Combiners are sometimes called Harmonic beamsplitters or Dichroic Filters.

For optimal filter performance:

When combining beams, the arrow on the side of the ring should point toward outgoing transmitted & combined laser beam.

When separating beams, the arrow on the side of the ring should point toward incoming combined beam and outgoing reflected beam.
