The LDM145P/670/1 is a Miniature Self-contained OEM Laser Diode Module emits a wavelength of 670nm. The MediBrite Compact series module is of medium visibility and can be seen in moderately bright background lighting conditions. It can be considered as an alternative to helium neon lasers in many applications and offers the additional benefits of superior ruggedness, compact size (16mm diameter) and greater efficiency. Internal connection of the laser diode to the module housing ensures good heat sinking and longer laser lifetimes. It uses a plastic lens that yields a circular spot and offers a lower cost unit at the lower powers.
