Astronomical Detectors


Design and construction of a CCD testbench for the University Complutense, Madrid.

This project was carried out in conjunction with Fractal SLNE. The test-bench uses an incandescent broad-band light source in combination with a monochromator and two filter wheels to provide programmable narrow-band illumination across the visible band. Light from the monochromator can be directed to an integrating sphere for flat-field measurements or sent via a small aperture directly onto the CCD under test for high accuracy diode-mode quantum efficiency measurements. Point spread function measurements can also be performed by interposing additional optics between sphere and the CCD under test. The whole system is under LabView control via a clickable GUI. The system has been used to obtain quantam efficiency data of an E2V CCD230.
