Semrock Inc.’s RazorEdge Dichroic beamsplitters reflect a laser wavelength incident at 45° and efficiently pass a broadband of the longer Raman-shifted wavelengths. The ion-beam-sputtering-coated beamsplitters are available for standard laser wavelengths, and they have an ultrasteep transition from reflection to transmission. The guaranteed transition from laser line to passband is <1% of the wavelength, regardless of polarization. They are made with dense, hard dielectric optical coatings for a high laser damage threshold, low temperature sensitivity and high performance, even in harsh, humid environments.
