This TE cooled HgCdZnTe Detector System is close to the sensitivity of liquid nitrogen cooled InSb, with the simplicity of TE cooling. It is one of our most popular IR detectors. It has a broad spectral response - 2 to 6 µm, and a 10 Hz to 140 kHz bandwidth. We also offer this detector packaged with collecting optics, for our TE Cooled HgCdZnTe Detectors for Oriel MIR8025 FT Spectrometers.

Ease of Use
Unpack the detector, connect it to Merlin, plug it into the mains and start using it. This all inclusive unit takes all the fuss out of working with high performance, cooled IR detectors. The detector head contains a TE cooled detector element and a preamplifier. The controller provides temperature control function and power for the preamplifier. We offer 110 and 230 V models.
Performance
Monolithic optical immersion of these detectors provides unmatched performance. A 42° field of view (FOV) serves most applications well, and 1 x 1 mm optical size allows effective signal collection. The typical responsivity of this detector system (Fig. 1) is DC responsivity; Merlin will read ~2.2 times lower voltage due to the RMS multiplier factor.
Mounting
Although the detector housing looks different than most other Oriel Detectors for Merlin, it has the traditional 1.5 Inch Series female flange for flange mounting, and M6 and 1/4-20 tapped holes for rod mounting.
Detector Systems
We offer two TE Cooled HgCdZnTe detector systems for Merlin; the difference is the power. The 70373 is the choice for 115 V operation; the 70374NS is for 230 V. Both systems include:
- TE Cooled HgCdZnTe detector element
- Detector Housing with buit-in preamplifier
- Power supply and temperature controller
- All necessary interconnecting cables
