LED Package and Module Intensity and Angle Testing
The LED package and module intensity and angle test solution is designed and developed in strict compliance with CIE 127:2007 Measurement of LEDs. It is dedicated to photometric distribution testing of LED packages and modules. Test conditions meet CIE 127 Condition A (far field) or Condition B (near field). Measures intensity, beam angle, luminous flux, beam diffusion angle, normal intensity, peak intensity, deviation angle and automatically plots intensity distribution curves and 3D intensity distribution. Uses 1 cm² national standard-grade photometer. Suitable for QC and laboratory. Optional radiation probes for IR/UV LED radiant intensity angle distribution.
