This Broadband Thermopile Detector allows the measurement of infrared light in the 0.19 – 20 µm range. This detector has a 12mm diameter sensor, measures up to 3 W (0.5 uW NEP). Please note that this detector head requires either an external display controller or computer interface (sold separately) to show the measured power. The price shown includes the detector head, post, post holder, and base only.

This thermopile is recommended for smaller light sources (collimated 500W arc lamps and below) and standard solar simulators (<5 Suns, <500 mW/cm2).

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 or PS-1 590-0006 when another lock in amplifier is used).
To connect this detector to a Sciencetech monochromator use the cryogenic detector mount P/# 125-8016

This Broadband Thermopile Detector allows the measurement of total broadband radiation emitted by a light source. It could also be used to measure the light power density on a surface (in W/cm2) which is particularly useful for uniformity measurements and for checking solar simulator performance. This detector has a 19mm diameter sensor and picks up all wavelengths between 190-11μm (UV-VIS-IR). Please note that this detector head requires either an external display controller or computer interface (sold separately - see below) to show the measured power. The price shown includes the detector head, post, post holder, and base only.

This thermopile is recommended for high-powered light sources (such as focused 500W + arc lamps) and concetrator solar simulators (5 Suns +, 500 mW/cm2).

The cryogenic receiver modules offer the ultimate in sensitivity for any given wavelength range as well as maximum immunity to EMI, microphonics, and accidental mishandling. The standard EOS dewars, side-viewing or down-viewing, can be provided with built-in amplifiers for any of the photodiode or photoconductor components. Depending on the specific detector and sensitivity requirements, parts of the amplifier may be cooled along with the detector.

These cryogenic modules are unique in the industry in providing the ultimate in sensitivity, EMI immunity, and low microphonic noise. The standard units contain switchable gains, BNC outputs, and shielded power connections. Custom options include offset control, additional gain control, and multi-stage amplifiers.
