Light Measurement System

altLabsphere (North Sutton, NH) offers the HalfMoon Total Forward Spectral Flux Measurement System designed for manufacturers of LEDs, light fixtures, and displays. Available in standard 12, 20, and 40 inch diameters, the HalfMoon system provides an alternative to integrating sphere photometer and goniophotometer methods of measuring total forward spectral flux of forward emitting lamps, luminaires, and displays. The compact design creates a virtual integrating sphere by pairing an interior mirrored surface cap with half an orb coated with Labsphere’s highly reflective diffuse Spectraflect® material. The system saves space, minimizes absorption errors, and facilitates quick sample changes.
