As part of a project, CLTC designed and built a mini-goniophotometer for The Watt Stopper. The goniophotometer is used to measure photosensor response throughout a 180-degree view.

Upon completing the build out of the mini-goniophotometer, CLTC provided technical consultation which involved measuring the angular sensitivity of alternative photosensor designs. The mini-goniophotometer can be used in laboratory photosensor product development and performance evaluations.
