For use with 3-pin or 4-pin TO-Can Laser Diodes

Through the use of the rear panel switches, the LDM-4405 can be adjusted to match most 3-pin and 4-pin TO-Can laser diode configurations, with the socket pin configuration shown on the right.  The LD and PD sockets can be toggled to either anode and cathode position, with a two common pin sockets in-between.  Please contact our Newport sales team for any questions you may have on laser diode compatibility, or choose between our selection of TO-Can diodes on

Universal Optical Post Mounting

The fixture is compatible with both imperial and metric optical table post mounts. The compact profile of the LDM-4405 provides for convenient mounting on an optics table and the unobstructed access to the laser window allows space for aligning collimating optics.

Model LDM-4405 (Mounting Base and Post/Post Holder not included)

Compatible with ILX Lightwave Laser Diode Instrumentation

Standard interconnect cables allow for quickly setting up the LDM-4405 with any ILX Lightwave current source or temperature controller. All connections including electrical and nitrogen purge are conveniently located on the back of the LDM-4405. Two switches allow the user to quickly configure the LDM-4405 for most TO-Can pin outs.

Affordable, Convenient Control of TO-Can Laser Diodes

When the LDM-4405 TO-Can Mount is paired with the LDX-3412-120V Laser Diode Driver and LDT-5416 Temperature Controller, it provides an affordable test setup for precision current and temperature control of TO-Can laser diodes. The LDM-4405 cover plate provides convenient clamping of TO-Can laser diodes to the cold plate by integrated O-ring and captive screws.

Nitrogen Purge

A nitrogen purge system is incorporated to keep the laser free from condensation when operated in a humid environment.
