About Laser Diode Modules

Our laser diode modules feature a rugged, compact design that is suitable for industrial or laboratory uses. Heat dissipation is handled by passive radiation through the case and mounting bracket. Integrated electronics protect the diode from reverse wiring and line noise that would otherwise destroy it.

For heat sink considerations, the laser diode module body is positively charged. Please keep this in mind when designing your device.

About Lenses

Adjustable focus allows you to project the sharpest beam pattern possible: this is critical for projecting lines and crosshairs. Glass lenses will render a more uniformly focused beam pattern than plastic ones. Plastic lenses, however, are lower in cost and may be sufficient for some applications.

Red and Green Laser Considerations

The human eye perceives the light emitted from a 1mW 670nm laser as bright.

Laser light at 650nm is perceived as brighter, and 635nm is seen as the brightest red.

Green laser light is significantly brighter than red laser light. All other factors being equal, the unaided human eye will perceive greeen laser light as over 8 times brighter than the common red laser (at 650nm). Green lasers are being adopted as a replacement for HeNe lasers. Along with increased visibility, many OEMs are enjoying the benefits of offering green lasers as a premium option.
