IR-628 Infrared Photosensitive Automatic Tester IR628 is used to measure the absolute photoelectric sensitivity and the receiving angle of the photosensitive tube, and can draw the relative sensitivity distribution curve in different angles. Main characteristics： The photosensitive receiving tube moves in a circle around the transmitting tube on the spherical surface at a certain distance from the transmitting tube. During the movement, the photocurrent characteristics of the photosensitive tube can be test. 1)Adopt high precise LED mechanical positioning device and integrated design center alignment system, high measurement accuracy; 2)Multiple level of scanning interval are selectable, which can meet the measurement requirements of different accuracy; 3)Adopt constant current power source to the transmitting tube, which is automatically adjusted by microcomputer through D/A with high accuracy. Parameter 1）Voltage range ：0V-10V 2）Optical current test range：200nA-20mA, 4level 10times 3）Goniometer scan range：±10°-±90°(selectable) 4）Goniometer angle accuracy：±0.05° 5）Programmable current range ：0.1mA～2000mA 6）Forward current range：0.10mA～99.99mA～2000.0mA
