Edge Filters

RazorEdge Raman Edge Filters
Semrock RazorEdge long wave pass Raman edge filters are available in three grades. RazorEdge short wave pass edge filters in two grades. These are determined by the "Transition Width". These are the highest performance edge filters available for Raman spectroscopy, with edge wavelengths from 224nm to 1319nm. Now you can see the weakest signals closer to the laser line than you ever have before. RazorEdge filters have deep laser-line blocking, ultra-wide and low-ripple passbands, proven hard-coating reliability and high laser damage thresholds. These filters have a 10-year guarantee and are available on a 30-day free trial.

BrightLine Edge Filters
Semrock BrightLine general edge filters are high performance, high reliability individual fluorescence edge filters optimised for use in a variety of fluorescence instruments. Parts denoted with a "-D" are unmounted. Parts with a "/LP" in the part number are long-pass filters and "/SP" are short-pass filters. These filters have a 10-year guarantee and are available on a 30-day free trial.

EdgeBasic Long Wave Pass Laser Filters
Semrock EdgeBasic value long wave pass filters for lasers offer a combination of performance and value for applications in fluorescence imaging and measurements, and Raman spectroscopy. This group of filters is ideal for specific Raman applications that do not require the measurement of the smallest possible Raman shifts, but do demand exceptional laser-line blocking and high transmission over a range of Raman lines. These filters have a 10-year guarantee and are available on a 30-day free trial.
