Model 2510 TEC SourceMeter instrument enhance Keithley's CW (Continuous Wave) test solution for high speed LIV (light current-voltage) testing of laser diode modules. These 50W bipolar instruments were developed in close cooperation with leading manufacturers of laser diode modules for fiberoptic telecommunications networks. Designed to ensure tight temperature control for the device under test, the Model 2510 was the first in a line of highly specialized instruments created for telecommunications laser diode testing.

It brings together Keithley's expertise in high speed DC sourcing and measurement with the ability to control the operation of a laser diode module's Thermo-Electric Cooler or TEC (Peltier device) accurately.

Supplied with: User's Manual and Input/Output Connector.

Applications: Control and production testing of thermoelectric coolers (Peltier devices) in:

• Laser diode modules
• IR charge-coupled device (CCD) arrays and charge-injection devices (CID)
• Cooled photodetectors
• Thermal-optic switches
• Temperature controlled fixtures
