Whereas our self-contained modules include the diode, optics, and driver in a single case, our SPM series separated geometry lasers house the diode and optics in their own head assembly, separate from the driver. This flexible configuration not only enables users to mount the unit in tight spaces where larger, self-contained modules couldn't fit, but it allows for a variety of laser head and driver combinations.

For those in need of a laser with separated geometry and modulated output, our SPMT is available.

Users of our SPM series lasers have a choice of the following drivers.

•• LDP201: This driver is designed for lasers up to 150mA and 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 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 when those lasers 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.

And the following laser heads are available.
