These new high performance RazorEdge 45-degree dichroic filters complement Semrock’s unique family of 45-degree filters, including versions of its StopLine notch filters, which reflect discrete laser lines incident at 45 degrees while passing both shorter and longer wavelengths, and Semrock’s equally unique family of MaxLine laser-line filters which pass discrete laser lines incident at 45 degrees while reflecting both shorter and longer wavelengths.
“The popularity of our standard normal incidence RazorEdge filters has frequently prompted calls for a complementary 45-degree version, and we have responded with a state-of-the-art solution,” said Dr. Turan Erdogan, CTO of Semrock. “Achieving this level of performance at 45 degrees is particularly difficult because of polarization splitting, but was realized as a result of our recent engineering advances. At Semrock we never stop innovating.”
These new dichroic products are available for standard laser wavelengths and generally ship from stock. All of Semrock’s filters are made with dense, hard dielectric optical coatings for high laser damage threshold, low temperature sensitivity, and permanent performance, even in harsh, humid environments.
