Liquid-nitrogen-cooled InSb detectors for near- and mid-infrared spectroscopy and nanosecond time-resolved measurements.
DInSb series detectors are liquid-nitrogen-cooled, side-window InSb photodetectors covering 1–5.5 µm. The DInSb5-De02 is a current-output detector for routine measurements with an optional preamplifier, while the DInSb5-HS adds an integrated 20 MHz preamplifier with a rise time below 25 ns for infrared time-resolved work with an oscilloscope.
Key Features
- LN2-cooled side-window InSb detectors, 1–5.5 µm
- DInSb5-De02: Ø2 mm active area as standard, with Ø1, Ø4 and Ø7 mm options
- DInSb5-HS: integrated 20 MHz preamplifier, rise time below 25 ns, for ns-scale detection with an oscilloscope
- D* of 1×10¹¹ cm·Hz½/W at peak wavelength and 1 kHz
- Higher sensitivity with a preamplifier and lock-in amplifier (DInSb5-De02)
- Dewar mounts conveniently on the spectrometer; one liquid nitrogen fill lasts about 8 hours
- Fits the manual slit of Omni-λ series spectrometers
Typical Applications
- Near- and mid-infrared spectroscopy
- Infrared time-resolved measurements
- Infrared photoluminescence
- Lock-in detection of chopped IR signals
