Sciencetech's proprietary wideband detector design comes packaged in our standard "hockey puck" enclosure (2" diameter x 1" high) and is connectorized to be powered directly from the Stanford SR-810/830 type lock-in amplifiers,
The spectral range is limited by high density polyethylene window.
The detector WILL saturate on the visible light from the lamp. After alignment, cover the entire input opening of the detector head with thin black polyethylene to prevent undesired visible light from overloading the detector.
This detector is suitable for direct connection to Stanford SR-830 lockin preamp power. When using the Stanford lock-in, the signal overload indicator will light just before the detector saturates.The SCIDTGS-PE detector is suitable for testing FTIR alignment and material transmission measurements without special cooling.
Upon installation, the optical system MUST be re-aligned to image the iris of the light source onto the detector element. This may require rotating the entire detector head to an optimum position and/or adjusting mirrors and re-focusing.
Element size 2.0 mm dia.
Spectral bandwidth Limited by High Density Polyethylene window

This product consists of the Sciencetech SOL-METER and our SSIVT-REF sun calibrated reference detector. The SOL-METER is a digital meter for use with solar calibrated detectors such as detector models SSIVT-REF or SC-LT. The meter converts detector measurements to a Sun value. It has a handheld meter that is compact, has a sturdy design, and is appropriate for indoor or outdoor applications.
The Sciencetech Reference Detector, which is an integral part of solar simulator calibration and solar cell I-V characterization, consists of a calibrated solar detector made of silicon.
The Reference Detector comes with calibration data taken by Sciencetech, calibrating it to a NIST-certified solar cell, on an accompanying certificate. It reads solar simulator irradiance in "sun" units; one sun is equal to 1,000 W/m^2, at 25 degrees Celsius and Air Mass 1.5 Global.
This tool's primary use is the testing of photovoltaic cells under standard conditions.

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).
