4700 - Photodiode Characterizer Complete PD Measurement System. The 4700 Photodiode Characterizer is a complete photodiode test system. It will characterize PDs or APDs (upcoming) without the need for additional power supplies. It is this simple: connect your device and press start. Like the dBm Optics optical power meters, the dBm Optics photodiode meters employ an electrometer-based design. 

VS9310 - Solar Cell Life Time Test System A Completed Solar Cell life time test system consists of: --- Multi_Channel Programmable Power Source --- Solar Simulator, and Photodiode Sensor --- Computer with Data Acquisition Software --- Test Device Holder & Jig

2500INT-SMA - Integrating Sphere with Germanium Detector, 2-inch 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.

SLS 9400 - FPD Colorimeter The color sensor utilizes four extremely stable colored glass filters in conjunction with high quality silicon photodiodes. The resulting response of this combination accurately replicates the CIE standard observer (tristimulus) functions. This allows the system's performance to be independent of the phosphor set under test. The colorimeter compensates for any scan rate and works for all types of displays, including LCD, LED, CRT, Projection, and even HDTV. The detector head is housed in an ergonomically-designed package with a nonslip scalloped grip. It is completely non-contact and polarization decoupled. A standard 1/4-20 post mount is included for added mounting convenience.
