Keithley instrumentation makes it easy to build a LIV (light-current-voltage) system to test laser diode modules cost-effectively.

• Fiber Alignment Photodiode Meter 2502: High speed analog output enables LIV testing at the fiber alignment stage.
• 2520 Pulse Laser Diode Test System: Synchronizing test system providing sourcing and measurement capability for pulsed and continuous LIV test.
• TEC SourceMeter SMUs, 2510 and 2510-AT: Ensure tight temperature control for laser diode modules by controlling its thermo-electric cooler.
