HM series















 
Total Luminous Flux Measurement System HM series  
Feature
  • Lighting direction is changeable, making actual lighting position attainable.
  • No self absorption error because only the illuminant is located in the integrating sphere.
  • Double sensitivity compared with conventional integrating sphere
  • Best suitable for surface illuminant (2pi light source)
  • Fixture is located outside hemisphere, making sample temperature control easy. (High brightness light source)
  • Suitable for big lighting device since the shadow of device itself can be minimally eliminated.(Device size up to one third of sphere diameter)
