The OPM150G10 is a large area germanium photodiode detector head, compatible with the OPM150 series of optical power meter.

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.

- Output receptacle: optional SMA fibre receptacle for spectrometer

- Calibrated absorbing attenuators: OD1, OD2, OD3

- Calibrated diffuse reflecting attenuators: OD1, OD2, OD3

- Adapters for tube systems

- Adapters for fibre inputs: FC, SMA, f1.25 ferrule

- Aperture reducer: f7mm (standard iris aperture)

Which detector is best for measuring YAG-lasers at 1064nm?

The choice of detector is affected by several parameters: beam size, power and wavelength. For use at 1064nm there are two choices available: OPM150G10 (or G5) and OPM150UVS. The G10 version is more expensive than the UVS version. However, it is more accurate since the responsivity of the UVS detector is temperature dependant at wavelengths beyond 900nm – which includes 1064nm. The user must consider this price-to-performance aspect for the application.

Further information on the temperature dependence of the G10 detector is given in the respective tutorial on this topic.
