Keithley Instruments 2500INT-2-Ge Overview

The model 2500INT-2-Ge is an integrating sphere with a 2-inch germanium detector. The 2500INT Integrating Sphere is the latest addition to the Keithley 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 the Keithley 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.

• Spectralon® sphere interior ensures high reflectivity
• Part of the Keithley high throughput system for production testing of laser diodes and LEDs
