Liquid-nitrogen-cooled MCT detectors for mid-infrared spectroscopy and fast infrared time-resolved measurements.
DMCT series detectors are liquid-nitrogen-cooled mercury cadmium telluride (MCT) photodetectors covering 2–22 µm. The DMCT(x)-De01 models are offered with long-wavelength cutoffs of 12, 14, 16 or 22 µm for routine measurements with a preamplifier and lock-in amplifier, while the DMCT12-HS has an integrated 20 MHz preamplifier and a rise time below 50 ns for time-resolved work.
Key Features
- DMCT(x)-De01 in four spectral ranges: 2–12, 2–14, 2–16 and 2–22 µm
- DMCT(x)-De01 models require a preamplifier and lock-in amplifier; -PA versions come with a matched preamplifier
- DMCT12-HS: integrated 20 MHz preamplifier, rise time below 50 ns, connects directly to an oscilloscope
- Minimum D* from 5×10⁹ to 3×10¹⁰ cm·Hz½/W, depending on model
- 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
- Mid-infrared spectroscopy
- Infrared time-resolved measurements
- Infrared emission and photoluminescence measurements
- Lock-in detection of chopped IR signals
