RazorEdge® Short Wave Pass Filters

Ultrasteep, for unparalleled discrimination

RazorEdge short-wave-pass filters are available in two grades determined by the "Transition Width," which is the guaranteed maximum difference between the laser wavelength (at which the attenuation exceeds optical density 6) and the filter edge-wavelength at the 50% transmission point, and the typical "Edge Steepness," which is the actual steepness of a filter measured from the OD 6 point to the 50% transmission point.

For the most discriminating Raman measurements, eliminate laser spectral noise leakage by cleaning up your laser spectrum with a matched MaxLine laser clean-up filter.
