    Single Channel Detector

    Sciencetech Single Channel Detectors

    Detector Material and Spectral Region

    Single channel detectors typically offer the smallest noise equivalent power (NEP values) and highest sensitivity levels. Single channel detectors are the best choice when you need to accurately measure extremely low light levels. Line and area detectors are typically used when measuring fast phenomena across multiple wavelengths (in a spectroscopic system).

    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 are required before measurements can be performed.

    This is a room-temperature detector for use with the SPS-300. This includes the DTGS detector with a mounting flange, but requires the use of a dual-phase lock-in amplifier (sold separately). Sciencetech's wideband detector design comes packaged in a mounting flange compatible with our SPS-300. It is connectorized to be powered directly from the Stanford SR-810/830 type lock-in amplifiers with a detachable cable. The spectral range is limited by window selection. This detector comes with a HDPE window standard.

    Element size: 2.0 mm dia.
    Spectral bandwidth: 16 to 100um (for HDPE window, other window materials available)
    Sensitivity: 200 V/W
    Frequency response: 10Hz - 265Hz (-3db points)
    N.E.P.: 5x10-10 watts (@100Hz)
    Power requirements: +/- 15 to +/- 24 volts max @ +/- 8 mA max.
    Power connections:
    DB-9M
    Pins 2,3,4,5,9 no connection
    +V In Pin 1
    -V In Pin 6
    Common Pin 7
    Case GND Pin 8
    Signal Connection: BNC

    Suitable for direct connection to Stanford SR-810/830 lockin preamp power (not included).

    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 (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 500W 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).
