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.
Values are transcribed from the archived product table and diagrams. Confirm the final detector, electronics and spectrograph interface for your configuration.

Integration and compatibility
Use these checks to connect DInGaAs Series to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Spectral response
- Spectral range: 800–1700 nm / 800–2600 nm · Peak responsivity (minimum): 0.9 A/W / 1.1 A/W
- Responsivity varies strongly across the stated band. Read the figure at your own wavelength rather than at the peak the headline range implies.
- Active area
- Active-area diameter: 3 mm
- Active area sets both the alignment tolerance and, through capacitance, the achievable bandwidth. A larger element is easier to hit and slower to read.
- Output and bias
- Signal output: Current
- Confirm whether the module is biased and amplified internally or expects an external supply and transimpedance stage. The two builds are not interchangeable and the wrong assumption destroys detectors.
