|
| 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)
