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.

Why choose InGaAs over Germanium?

The choice of detector is affected by several parameters: beam size, power and wavelength. In general a photodiode will give best results when used at wavelengths below the wavelength of peak sensitivity. Although the head may operate at higher wavelengths, the sensitivity of the photodiode will be strongly temperature dependant. Thus, for wavelengths beyond 1550nm, InGaAs will be the material of choice.

Also, at wavelengths below 800nm, our visible enhance InGaAs exhibits markedly higher responsivity than Germanium.
