| Light colour | red |
| Peak wave length | 635 nm |
| Output power | 10 mW mW |
Laser diode, wavelength 635 nm (red-orange) and 9 mm standard package. The relatively short wavelength improves beam visibility by a factor of 3 compared with 670 nm. For a complete laser unit, the laser diode requires a holder, collimator and drive module.
