The LQ series laser modules are designed to provide a compact laser unit at a minimum price. They feature automatic power control (APC) circuitry for a regulated output power over their entire input voltage range. They also have reverse polarity protection.
NOTE: The case of the laser module and the positive input lead are electrically common.
