Optical metrology of solar reflector panels with a high density Hartmann sensor
Authors : Eduardo Bendek
There is a need to test replicated glass reflector panels molded at the Mirror Lab for a solar concentrator. The goal is to map the residual errors of the surface so the mold surface can be improved. A new metrology process has been developed since normal methods are too sensitive or cannot resolve the small scale ripples formed in the molding process.
