The OPM150VIGASMA is an InGaAs photodiode detector head, compatible with the OPM150 series of optical power meter. The special design of the material gives high sensitivity down to 400nm. This compact unit is designed specifically for measurement of power out of SMA-connectorized fibres only. The fibre receptacle, photodetector and calibration memory chip are all contained in the connector body.
When connected to the OPM150 base unit, each head is automatically recognized and its individual calibration data are uploaded to the system.
