Model 2500INT-2-IGAC Integrating Sphere w/Cooled Indium Gallium Arsenide Detector, 2-inch

Part Number: 2500INT-2-IGAC
Products available for purchase from our web store may include U.S. pricing displayed and can be ordered online by U.S. customers for end use in the U.S. only.

Key Features and Benefits:
  • Choose from silicon, germanium, or cooled indium gallium arsenide detectors
  • Spectralon® sphere interior ensures high reflectivity
  • Part of Keithley's high throughput system for production testing of laser diodes and LEDs

The Model 2500INT Integrating Sphere is the latest addition to Keithley's growing line of solutions for LIV (light-current-voltage) testing. When connected via a low noise triax cable to the Model 2502 Dual Photodiode Meter included in Keithley's LIV Test System, the integrating sphere allows the system to make direct measurements of optical power, with results expressed in watts. The integrating sphere simplifies production testing of laser diodes (LDs), light emitting diodes (LEDs), and other optical components by eliminating common optical power measurement problems related to detector alignment, beam profile, polarization, and back reflection.
