The LDM-4409 Laser Diode Mounting Fixture provides acompact, easy to use solution for mounting and temperature
control of C-mount laser diodes. The 4409 features atemperature control range of +10oC to 85oC for lasers withup to 10W optical power. Optimized thermal resistance
between the laser diode and the temperature controlled hot
plate minimize the temperature rise of the laser.
The LDM-4409 has been optimized for pre and postburn-in characterization in R&D or manufacturing test
applications. A unique spring loaded clamping mechanism
facilitates device insertion and removal. A 1mm clearancezone in front of the C-mount device allows for measurementof highly divergent beams and easy integration into mostmeasurement set-ups. These mounts are compatible withILX Lightwave current sources and temperature controllers
with standard laser and temperature controller connectors
for quick setup.

Active Temperature Control
For fast, accurate characterization of yourC-mount devices, the LDM-4409 comes with an
integrated 120W TEC and cooling fan. The highpower TEC has the thermal performance to dissipate
the head load associated with high power C-mountlaser diodes.

Quick Device Insertion and Removal
The LDM-4409 incorporates a unique clamping
mechanism for quick and effortless device insertionand removal without the need for any additional tools.
The spring loaded device locates and clamps theC-mount device repeatably to cut down adjustment
time of measurement devices and optics.

Repeatable, Low Thermal Resistance

the C-mount device and the mounting block. A springloaded clamping mechanism provides repeatable,
constant clamping pressure on the C-mountdevice. Further reduction in thermal resistance canbe achieved by clamping the device with a #2-56
screw through the center of the device. Low thermal
resistance eliminates measurement inconsistencies
due to temperature differences between the mountand the device under test.

Unobstructed Access to the Front
The LDM-4409 design facilitates integration
into optical test and measurment systems througha 1mm clearance zone from the front of the laser.
Measurement devices such as integrating spheres
as well as optics can be located in close proximity
to the front of the laser.

Careful attention to the LDM-4409’s mechanicaldesign results in a low thermal resistance between
