Optical Path Converter

There are many LED manufactories using two integrating spheres and one spectrophotometer to do test. The previous testing way is: when you use big sphere to test, the customer need to connect the detector cable and optical fiber from the Spectrophotometer to the big sphere, after the calibrating and then you can do the test. When you use the small sphere, you need to take away the detector cable and optical fiber from the big sphere to the small sphere, then need to calibrate again… It is too troublesome to take out the detector cable and optical fiber between the big sphere and small sphere, and you need to calibrate again for every change. The frequent change will also shorten the life of the detector cable and optical fiber.

Parameter measured under normal temperature: 1) β(0-99) 2) Switching time T(0.01μs-99.9μs), including Tr, Ts, Tf 3) VCES(0-2V), VBE(0-2V) 4) Leakage current ICEO(0.01μA-99.9mA) 5) Withstand voltage BVCEO(50V-650V) • Parameter measured under high temperature: VBE, β, ICEO • Compare the measuring results VBE, β, ICEO gotten under normal and high temperature, to those changes exceeding the preset limits, the selector alarms to let operator to pick them out • Divide T and β into several groups, selector can display group number and alarm when measured values of VBE, β, ICEO exceed the limit, indicating the unqualified item • Freely adjusting or setting test conditions according to requirement A. β testing: Ib; three different Ib current: 0.1mA、1mA、10mA B. Switching time test: Ic; 4 different Ic current: 0.5A、0.25A、0.1A、0.05A; the corresponding current Ib: 0.1A、0.05A、0.02A、0.01A C. Heating condition for transistor: 1) Heating voltage: 5 ~ 20V Continuously adjustable 2) Heating current: 0.05 ~ 2A Continuously adjustable 3) Heating time: 0 ~ 9.9s Continuously adjustable • Dividing value and limit value, freely set and automatically saving to any power cut; the  instrument can save 20 different settings, choose one setting when using it. • Measured values displayed in four windows which are easily read and printable.
