The LDM850 compact laser source is well suited to benchtop optical experiments. The Ø1.40" by 5.8" housing contains a laser diode, collimating lens, and power controller. Each LDM module includes a built-in shutter and features SM1 internal thread for mounting with an extensive range of optomechanical devices from lens tubes to lens mounts.

Besides the mechanical shutter, the module also features a remote interlock connection and key-lock power switch. The laser module has an enable/disable toggle switch, laser on indicator LED, and top-located power adjustment pot controller. The power can be adjusted from 0 to 20 mW. The output of this laser diode is polarized. When the Laser Enable button is facing up, the light will be horizontally polarized. Each LDM comes with a universal power supply.
