The photometric and colorimetric evaluation of ultra short throw laser projectors is vitally important. Since the light from them enters illuminance meters with a large angle, the angular dependence of illuminance meters plays a significant role. We developed RGB laser meters and confirmed they have a proper angular dependence.
