SPM Separated Geometry Lasers-Image

Members of the SPM family of lasers not only offer a rugged build, aspheric glass optics, and a versatile nature, but they also feature an ultra-compact separated head. With a diameter of only 5.80mm, the SPMC is the smallest PTI head available. Also available are the SPM head (with a diameter of 12.67mm) and the SPMB head (with a diameter of 6.99mm). Users of SPM series laser heads have a choice of the following power supplies.

LDP201: This power supply - designed for lasers up to 150mA - may operate in either constant current or automatic power control mode. Built-in 3/4 turn potentiometers allow users to adjust the laser power or drive current, depending on the mode of operation. DVM-compatible test points enable monitoring of the laser drive current or photodiode feedback current during operation.

LDP214: The LDP214 is designed to drive lasers up to 120mA that incorporate a back-facet monitor diode. The unit operates in automatic power control mode and, therefore, will adjust to environmental changes to maintain a constant output power. A built-in 3/4 turn potentiometer enables users to adjust the laser power from 0 to the maximum, factory-set laser output.

LDP234: Designed to drive P-type laser diodes up to 120mA, the LDP234 operates in constant current or automatic power control mode. A built-in 3/4 turn potentiometer enables users to adjust the laser power from 0 to the maximum laser setting.
