(MCT-14-20-E-LN) Detector - MCT Cryogenic Receiver, LN2 cooled 2x2mm Square

Sku: 584-6002

Quick Overview

This single element detector is effective at sensing wavelengths between 2,000nm and 15,000nm. Please note that it is available in various sizes and includes a dewar to hold liquid nitrogen (to lower dark current and improved signal to noise). To operate this detector liquid nitrogren is required. As with most IR detectors MCT detectors are coupled to AC preamplifiers which means they detect changes in light levels. Generally the light signal being detected is modulated with a chopper or the source itself is modulated, such as a pulsed laser source. When using a chopper to modulate the input signal generally a lock-in amplifier is used to demodulate the signal. The output signal from the MCT is an analog signal available through a BNC on the back of the detector housing. Since the signal is analog, an optional 12-bit or 16-bit data acquistion system and software is available (sold separately).
The MCT detector includes a preamplier. This system also requires a power supply (sold separately, compatible with the PS-1/LIA 590-0106 when a lock in amplifier and power supply is required or PS-1 590-0006 when only a power supply is required).
To connect this detector to a Sciencetech monochromator use the cryogenic detector mount P/# 125-8016
