The LDM-4990 TO-Can Laser Diode Mounting Fixture
provides a compact, easy to use solution for locating andtemperature controlling 9mm, 5.6mm and 5.4mm packaged
laser diodes. These mounting fixtures feature an accessdoor for easy device insertion and clamping, configurable
pin headers for varying package pin-outs, and active
temperature control with a temperature control range of-20oC to 85oC. High positional and thermal resistancerepeatability ensure consistent device testing and repeatablemeasurements.
The LDM-4990 has been optimized for pre and postburn-in characterization in manufacturing test applications
with easy of device insertion and removal, a wide temperature
control range and easy integration with ILX power andwavelength measurement instruments. These mounts arecompatible with most ILX Lightwave current sources andtemperature controllers with standard laser and temperature
controller connectors designed into the fixture.

Integrated Power Measurement

For fast, accurate characterization overtemperature of your TO-Can devices, the LDM-4990
comes with an integrated TEC module with watercooling channels for a control range of -20oC to 85oC.
The design minimizes the thermal path between thelaser and the TE modules and locates the sensor
close to the laser for optimal control. A nitrogen purge
system is incorporated to keep the laser frost-free at
sub-zero oC temperatures. Standard ILX Lightwave
9-pin connectors are provided for compatibility withILX Lightwave temperature controllers.

Another unique feature of the LDM-4990 includes
an optional mounting post compatible with ILX OMH
power and wavelength heads. The measurement
head attaches easily to the mounting fixture with one
threaded fastener. Once the head is attached, simply
rotate the head over the device under test and it willlock in place with spring loaded detent pins. Choosebetween a variety of measurement heads for shortor long wavelength devices.
For an LIV test system, the LDM-4990 alongwith ILX laser diode current sources, temperature
controllers, and power and wavelength meters, canbe configured in minutes.

Quick Device Insertion and Removal
The LDM-4990 incorporates a door mechanism
for quick and effortless device insertion and removal
without the need for any special tools. The door
contains a unique device for quickly selecting,locating, and clamping different sized TO-Can
packaged lasers.
