Design and integration details
- Room-temperature InGaAs detectors covering standard and extended NIR ranges.
- Both models share the same mechanical construction.
- Three-millimetre active-area diameter with current output.
Application and connection notes
- Select the 1700 model for the standard InGaAs band or the 2600 model for extended-NIR coverage.
- A current preamplifier may be required by the downstream acquisition electronics.
