Ontwerp- en integratiedetails
- Liquid-nitrogen-cooled MCT detector family with cut-offs from 12 to 22 µm.
- Routine De01 models accept an optional preamplifier; the high-speed model integrates one.
- DMCT12-HS uses a 20 MHz preamplifier for time-resolved measurements and direct oscilloscope connection.
Toepassings- en aansluitnotities
- Routine DMCT(x)-De heads require a preamplifier and lock-in amplifier when supplied without the -PA option.
- DMCT12/14/16/22-De01-PA variants include the original preamplifier.
- 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.
