IDEX Health & Science Semrock offers the widest selection of Raman spectroscopy related long pass and dichroic filters available, with edge wavelengths from 224 to 1550 nm. They offer the highest transmission and the lowest ripple, and are available with a range of edge steepness values, from the highest available to lower values, at a range of prices. These filters can be paired with MaxLine laser line filters for the best suppression of the laser background. Now you can see the weakest signals closer to the laser line than ever before.
