The VC2002L High Speed CMOS Line Scan Smart Camera can be used to control the laser scribing on thin-film solar cells. Thin silicon film coats a solar cell’s glass before being structured by a laser. The laser scribes conducting paths that run parallel and as close to each other as possible without touching. The camera acts as a monitoring system and checks P1, P2, and P3 scribes and with precision of 1 μm, controls the laser scribing. The sensor scans the laser line position at a 5 ms rate (thus providing 200 measurements per second.)
The camera transmits analysis data and scan results to an optional display monitor via an Ethernet or RS232 interface. The VC2002L contains the necessary analysis electronics to carry out all image processing steps and will only need to be connected to a PC for parameterization.
This high speed CMOS camera supports autonomous operation, external triggering with a constant exposure time, or a trigged exposure. It’s sized at 90 x 50 x 35 mm, which allows for easy integration into machines and plants. The camera is rugged, making it suitable for industrial environments. Additional information can be found on the available datasheet.
