Large Integrating Spheres
For measurement of high powered LEDs and sources, Avantes offers the AvaSphere-100, -150 and -200mm. The number corresponds with the internal diameter of the spheres in millimeters.
The 100, 150 and 200 models come with three ports: at 0, 90 degrees and NP. The port of your choice is fitted with a baffled SMA-905 connector, please specify when ordering. Either of the other two ports can be used for illumination or sampling. The default sample port sizes are typically 25% of the sphere’s diameter. Port plugs or reducers are available on request.
All spheres can be attached to spectrometers via fiber-optic cables and the entire system can be irradiance calibrated to measure total flux of a lamp under test.
