GL OPTI SPHERE 205

The ultimate solution for luminous flux and radiant power measurement of LEDs.

The GL OPTI SPHERE 205 has been designed for the measurement of Luminoux Flux and Radiant Power of LEDs and other light sources compliant with the recommendation of the CIE Technical Committee published in Technical Report CIE 127:2007. The geometry of the sphere allows the installation of different adapters to measure all kinds of light sources. Conforming to CIE recommendations front emitting diodes can be measured at the wall entrance in 2π geometry. Other types of LEDs should be measured at the center of the sphere in 4π geometry.

 

UNIQUE FEATURES

 

  • Measurement of LEDs compliant with CIE 127:2007
  • Universal lamp post
  • Geometry for front emitting diodes and other sources
  • Universal ports for SMA fiber optics or GL SPECTIS 1.0
  • Auxiliary light source for self-absorption compensation

 

USAGE

 

The entrance of the sphere is equipped with a precisely designed 50mm aperture which can be used in Partial Flux measurements of LEDs. For this application the test LED is installed outside the sphere at determined distance and the flux is measured inside the sphere. Appropriate accessories are available for specific measurement purposes. The GL OPTI SPHERE 205 features the auxiliary light source for compensation of the self-absorption effect of the test LED.


Reliable measurement of light

Inner walls of the sphere are coated with barium sulfate (BaSO4) which ensures high reflectance properties up to 97%. All GL O ptic s pheres a re u niversal a nd c an b e u sed w ith the GL SPECTIS 8.0 with fiber optics bundle or with the GL SPECTIS 1.0 with a proper adaptor installed directly on the sphere.

The GL Optic spheres are also available in 2 sizes:
– GLS 125 with 125mm diameter as a low-cost solution
– GLS 205 with 205mm diameter conforming to CIE standards for LED measurement.


All GL Optic spheres are universal and can be used with the GL SPECTIS 8.0 with fiber optics bundle or with the GL SPECTIS 1.0 with a proper adaptor installed directly on the sphere.
