Imaging the transmission of light through a crystalline silicon wafer with a silicon detector array

A simple experimental set up for capturing the distribution of light transmitted through a silicon wafer is presented. As sensing element a silicon based charge coupled device, CCD of a 4 Megapixel camera was used. The responsitivity of the camera in the optical NIR wavelength range was evaluated. The applicability of a pulsed Xenon arc lamp built into a photographer's flash light as light source was investigated. First results from transmission images proof the potential of these two components for further applications in the solar industry.
