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.

RazorEdge Long Wave Pass Filters – These filters are housed in a labeled, black-anodized aluminum ring with diameter 25 mm and thickness 3.5 mm. 50 mm diameter filters are also available.
