StopLine® Thin-film Single Notch Filters

RazorEdge filters are available in three grades determined by the "Transition Width," which is theguaranteed 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.

StopLine Filter Type	Passband Range (nm)	Laser-line Blocking
"E grade"	350 nm to 1600 nm	> 6 OD
"U grade"	0.75 x λ_Laser to λ_Laser / 0.75	> 6 OD
"S grade"	0.75 x λ_Laser to λ_Laser / 0.75	> 4 OD

StopLine single-notch filters are available from stock for the following laser wavelengths. Each filter is housed in a labeled, black-anodized aluminum ring with a diameter of 25 mm and a thickness of 3.5 mm.
