ORDER CODE – SPHERE: 20.220.00055


A 20mm inner diameter integrating sphere encorporating a germanium photodiode. This detector is compatible with the OPM150 series of optical power meter.

The SP20G detector consists of a 20mm integrating sphere and an M8 Germanium photodiode detector port. It is compatible with our OPM150 series of optical power meters. As the sphere is equipped with three output ports, two additional ports should be selected during configuration (fiber, photodiode or blind plug).

The head mechanics are designed to be compatible with various common optomechanics systems to allow simple integration. Various adapters for tube systems, camera objectives and optical fibres are available to further enhance the ease of integration.

When connected to the OPM150 base unit, each head is automatically recognized and its individual calibration data are uploaded to the system. In addition, the user may load up to 5 separate filter curves. Thus the dynamic range and functionality of the unit can be expanded while ensuring proper calibration.
