StopLine single-notch filters are available in three grades determined by passband range, laser-line blocking level, and notch bandwidth.
StopLine Filter Type | Passband Range (nm) | Laser-line Blocking |
"E grade" | 350 nm to 1600 nm | > 6 OD |
"U grade" | 0.75 x λLaser to λLaser / 0.75 | > 6 OD |
"S grade" | > 4 OD |
