Product Family Description

  • Polarization Insensitive
  • Hard Sputtered Coating
  • Multiple Sizes Available

TECHSPEC® Dichroic Laser Beam Combiners are designed to efficiently combine or separate multiple laser beams at a 45° angle of incidence. TECHSPEC Dichroic Laser Beam Combiners feature greater than 98% reflection and greater than 95% transmission at popular laser lines, yielding exceptionally low loss. Constructed from low autofluorescence substrates with hard sputtered coatings, TECHSPEC Dichroic Laser Beam Combiners are ideal for multi-laser fluorescence imaging and measurement applications, including laser microscopy and flow cytometry.

Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm2 @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.

All mounted TECHSPEC® Optical Filters have an arrow on the side of the mount that points to the filter-coated surface for quick reference. Filter oriented such that arrow points to filter coated surface S1. Anti-reflective (AR) coating is applied to S2.
