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. 

Lab Buddy - Optical Receivers For busy test stations or student labs, where users of different experience levels might be handling high value opto-electronics that are easily damaged by mishandling, order your photodiode or photoreceiver to be mounted in the Lab Buddy.

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.

40G - Optical Receivers Discovery Semiconductors introduced its first commercially available 40 Gb Dual-Depletion InGaAs/InP p-i-n Photodiode at the Optical Fiber Conference in Dallas, Texas, in 1997. Since that OFC, we have expanded our pioneering dual-depletion photodiode design for several cutting edge products such as Balanced Photodiodes for 40 Gb, and Ultra-fast photodiodes up to 60 GHz. Today, our 40 Gb product line has evolved to include PIN+TIA optical receivers, with both linear and limiting amplifiers. These receivers work up to 40 Gb from 1064 nm to 1650 nm for single mode applications, and additionally up to 25 Gb for 850 nm multimode applications. For 25 Gb data rates, these receivers come with an optional CDR. Additionally, we supply 40 Gb Integrated Balanced Optical Receivers for 40 Gb DPSK/DQPSK systems. For busy test stations or student labs, where users of different experience levels might be handling high value opto-electronics that are easily damaged by mishandling, order your photodiode to be mounted in our Lab Buddy instrument.

SLS-9400 - Tri-Stimulus Colorimeter The SLS 9400 tri-stimulus colorimeter consists of a color sensor and a handheld display unit. 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.
