We stock the widest selection of Semrock Raman-spectroscopy edge filters available, with edge wavelengths from 224 to 1550 nm. These filters are so steep and highly transmitting that they outperform even the leading holographic notch filters at less than half the price. Now you can see the weakest signals closer to the laser line than ever before.
