Half Moon Integrating Hemisphere Spectroradiometers Nov 16, 2009

A Half Moon spectroradiometer provides an ideal solution for measuring the forward (2pi) flux from solid state lighting. The device under test is placed at the sphere port which means that the body of the luminaire, the heat sink and any drive electronics remain outside of the chamber and don't absorb light. This results in improved accuracy compared with placing the sample within a full sphere.

A Half Moon spectroradiometer comprises the hemisphere, a CCD spectrometer and LightMtrX software which provides lumens, chromaticity, colour temperature and colour rendering data.
