Product Description
Opt Lasers 1.2 mW 405 nm Free Space Laser Diode Module features excellent divergence and beam size specifications. The laser diode driver provided with this module ensures precise control of laser diode current while maintaining high-speed modulation. Precise control of the temperature of the laser diode housing greatly improves power stability and ensures the long lifetime of the laser diode. This combination of beam specifications and current, temperature control makes this module a perfect choice for both scientific and industrial applications.
The module feautures possibility to mount thorlabs cage system adaptor. A cooling platform and PSU for this module are available for this module. If you want to add them to your other or have any other questions feel free to contact us.
