Compatible with both ANSI andmetric optical table post mounts
Unobstructed access to the front ofthe TO-Can laser diode
Nitrogen purge

The LDM-4405 Laser Diode Mounting Fixture provides acompact, easy to use solution for mounting and temperature
controlling TO-Can packaged laser diodes. The fixture
accommodates 5.6mm and 9mm TO-Can laser diodes with 3 or
4 pins. A wide temperature control range is accomplished by an
integrated thermoelectric module which provides for an active
control range of +10oC to 85oC with heat loads up to 500mW.
A nitrogen purge system is incorporated to keep the laser freefrom condensation when operated in a humid environment.
The LDM-4405 is compatible with ILX Lightwave current
sources, temperature controllers, and laser diode controllers
through interconnect cabling allowing for quick setup. The
fixture is compatible with both ANSI and metric optical table
post mounts. The compact profile of the LDM-4405 provides forconvenient mounting on an optics table and the unobstructed
access to the laser window allows space for aligning collimating
optics.

When the LDM-4405 is paired with ILX’s
LDX-3412 Current Source and the LDT-5412
Temperature Controller, it provides an affordable test
setup for precision current and temperature controlof 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 captivescrews.
Standard interconnect cables allow for quickly
setting up the LDM-4405 with any ILX Lightwave
current source or temperature controller. Allconnections including electrical and nitrogen purge
are conveniently located on the back of the LDM-4405.
Two switches allow the user to quickly configure theLDM-4405 for most TO-Can pin outs.
