    Single Channel Detector

    Sciencetech supplies and integrates a wide variety of single channel detectors. Detectors vary by a number of important parameters.

     

    Detector Material and Spectral Region:

    Semiconductor-type detectors are sensitive to the spectral region matched to the bandgap energy of the semiconductor. This means that detectors of different material types are sensitive to different wavelength regions.

     

    Temperature Control:

    Some detectors can be temperature controlled or require cryogenics such as liquid helium or liquid nitrogen in order to be operable.

     

    AC or DC Coupling:

    Some detectors are photoconductors and require modulated light in order to detect a signal. These types of detectors are listed as AC-coupled. Generally, for AC-coupled detectors, a lock-in amplifier (LIA) or demodulator is required before measurements can be performed.

    This Broadband Thermopile Detector allows the measurement of infrared light in the 0.19 – 20 µm range. This detector has a 12 mm 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 (such as the UNO-1, 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 500 W arc lamps and below) and standard solar simulators (<5 Suns, <500 mW/cm2).

    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).
