Design and integration details
- Liquid-nitrogen-cooled side-window InSb detector family.
- General-purpose current-output detector or high-speed voltage-output detector with integrated preamplifier.
- The high-speed model uses a 20 MHz preamplifier for nanosecond time-resolved measurements.
Application and connection notes
- A preamplifier and lock-in amplifier improve sensitivity for the DInSb5-De02.
- The source states that one liquid-nitrogen fill can maintain operation for approximately eight hours.
- Standard configuration is for a manual Omni-λ slit; contact us for motorized-slit integration.

Integration and compatibility
Use these checks to connect DInSb5 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: 1–5.5 µm
- 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: Ø2 mm / 1 × 1 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.
- Noise and cooling
- Cooling: Liquid nitrogen
- Compare NEP or dark current at the operating temperature and bandwidth you will actually use; both figures improve with cooling and degrade with bandwidth, so a single number without conditions is not comparable.
- Output and bias
- Preamplifier: Optional / integrated, model dependent · Signal output: Current / voltage, model dependent
- 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.
Technical FAQ
Integration questions for DInSb5 Series
What wavelengths does the DInSb5 Series detect?
