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 |
