It consists of a light-permeable screen with a monochrome camera suitable for measurements in the near infrared wavelength region – fully integrated in a light-proof housing suitable for lab and production applications. \\ SYSTEM SETUP The core functionality of the VTC 2400 is provided by a combination of the screen and the 5 MP infrared camera. The device-under-test illuminates the screen from one side and creates a spatially resolved mapping of the radiant intensity. The camera captures this distribution from its transmission profile. Consequently, the setup allows the measurement of angular distribution of the far field distribution of the VCSEL array or LED. Absolute radiant flux Angular and spatial distribution of the emitted light Opening angle Cross-section profile of the emission pattern Height of middle and outer peaks Identification of the highest intensity spot The system is equipped with a robust housing to protect the test system against dust and environmental light. The distance from camera to screen is fixed to 400 mm by default. The DUT can be placed in variable distance in front of the screen. As always with Instrument Systems, the overall system comes with an absolute radiometric calibration traceable to national standards (PTB). To verify compliance of the DUT with IEC laser safety standards, the VTC 2400 enables identification of the maximum intensity spot of the emission pattern. ~ The VTC 2400 comprises a monochrome camera and a lightpermeable screen to measure the radiant intensity distribution of infrared VCSEL arrays / LEDs. ~ The VTC 2400 is made for measuring and analyzing the 2D radiant intensity distribution of IR emitters.
