CHAPTER 2
Laser Diode Mounting
Laser diodes are extremely susceptible to damage caused by electrostatic discharge and
surge currents. To avoid early failure or damage to the device, workers and
workbenches must be grounded at all times when handling or working with laser diodes.
The LDM-4990 is designed to allow quick, easy insertion and removal of laser
diodes in a 5.4 mm, 5.6 mm and 9.0 mm TO-can style package. A unique access
door with a rotating device selector on the inside allows configuration of the mount
for any of these package styles; Figure 2.6.
Figure 2.6 LDM-4990 Access Door Device Selector
To adjust the 4990 for your device package, simply rotate the device selector so
that the correct o-ring is to the right and the device selector clicks in place. The
large o-ring is for 9 mm packages, the next counterclockwise position for 5.6 mm
packages, the final position is for 5.4 mm packages. For correct positioning of the
device selector be sure to rotate it two clicks between positions.
Be sure the mount is configured correctly for the can style before attempting to close the
access door. Incorrect configuration may damage the mount or the device.
