The Near Infrared Camera

VC4067/NIR Near Infrared Smart Camera is primarily for use with solar industry applications. Thanks to a unique sensor operation mode, the photosensitive technology ensures highly precise images at wavelengths up to 1,100 nm. As a result, the camera is optimally suited, e.g., for electroluminescence (EL) quality control tasks. It reliably detects and identifies defects such as micro cracks, shunts, and disconnected fingers. The resolution equals that of similar systems on the market without integrated intelligence. Unlike those, the cost-efficient VC solutions include all image processing electronics and do not require cooling systems. Thus, VC4067/NIR is much more efficient than comparable systems in the market.

Featuring an integrated 400 MHz processor from Texas Instruments, the VC4067/NIR has a computing power of 3,200 MIPS. The 2/3" CCD sensor has a 1,280 x 960 pixel resolution and provides a maximum frame rate of 14 fps and a freely programmable exposure time from 5 µs to 17 s. Standard configuration also includes four digital PLC inputs and four outputs and an SXGA video output.
