Large diameter visible and near-IR RazorEdge filters offer the same performance as our standard-size RazorEdge filters over 4x the area! They 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.

RazorEdge Filter Type	Guaranteed Transition Width (% of laser wavelength)	Typical Edge Steepness (% of laser wavelength)
"U grade"	< 1.0%	0.5%
"S grade"	< 2.0%	0.5%

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.

Long Wave Pass Filters – These filters are housed in a labeled, black-anodized aluminum ring with diameter 50 mm and thickness 3.5 mm. 25 mm diameter filters are also available as standard sizes. Custom-sized filters are available in one week.
