The OPM150VIGA is a small area 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 gives an exceptionally wide range of wavelengths covering the most common types in a single head.

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.

- 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

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.

On the downside, large area InGaAs detectors are prohibitively expensive. Thus, this material is generally limited to f3mm sensitive area.
