InGaAs avalanche photodiodes are used to detect light in the spectral range from 1100 nm to 1700 nm. They exhibit a significantly lower noise than germanium diodes.
These InGaAs avalanche photodiodes detect in the spectral range from 1100 nm to 1700 nm. IAG series APDs exhibit particularly high damage threshold values. Both come packaged in a TO-46 housing.
InGaAs-APDs are suitable for the spectral range from 1100 nm to 1700 nm. Compared to germanium APDs, they feature a significantly improved noise ratio, a higher bandwidth in relation to the active area, and advantages resulting from the increased sensitivity of up to 1700 nm.
All APDs in a TO-46 housing are available fibre coupled on an optional basis.
The IAG series exhibits a high damage threshold of >200 kW/cm². The responsivity of the detector peaks at 1550 nm and the active area is available in diameters of 80 µm, 200 µm, and 350 µm.
