Dichroic Edge Pass, Long Edge Ultra Steep Filter for Raman applications   

632.8 US LPF   

Iridian Ultra Steep Edge Pass filters deliver superior performance in spectroscopy experiments. Their hard dielectric coatings do not require cover glasses for durability, greatly improving the transmission levels when compared to traditional filters.

Designed to isolate one band of wavelengths from another by reflection or transmission, these filters are used to separate the excitation source wavelength from the emission wavelengths in Raman spectroscopy.

The high blocking of these edge filters improves spectral noise reduction by eliminating the need for additional filtering.
