The LDM-4990 TO-Can Laser Diode Mounting Fixture provides a compact, easy to use solution for locating and temperature controlling 9mm, 5.6mm and 5.4mm packaged laser diodes. These mounting ﬁ xtures feature an access door for easy device insertion and clamping, conﬁ gurable pin headers for varying package pin-outs, and active temperature control with a temperature control range of -20 to 85 C. High positional and thermal resistance repeatability ensure consistent device testing and repeatable measurements.The LDM-4990 has been optimized for pre and post burn-in characterization in manufacturing test applications with easy of device insertion and removal, a wide temperature control range and easy integration with ILX power and wavelength measurement instruments. These mounts are compatible with most ILX Lightwave current sources and temperature controllers with standard laser and temperature controller connectors designed into the ﬁxture.
For fasst accurate characterization over temperature of your TO-Can devices, the LDM-4990 comes with an integrated TEC module with water cooling channels for a control range of -20 to 85 C. The design minimizes the thermal path between the laser 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 C temperatures. Standard ILX Lightwave DB9 connectors are provided for compatibility with ILX Lightwave temperature controllers.
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.
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 will lock in place with spring loaded detent pins. Choose between a variety of measurement heads for short or long wavelength devices.For an LIV test system, the LDM-4990 along with ILX laser diode current sources, temperature controllers, and power and wavelength meters, can be conﬁgured in minutes.
