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
Sensitivity 133,000 volts per watt HDPE Window
Frequency response 8.8Hz - 265Hz (-3db points)

This single element detector is effective in sensing wavelengths between 1000 nm and 5500 nm. Please note that it is available in various sensor area sizes and includes a dewar to hold liquid nitrogen for significantly lower dark current and improved signal to noise. The output is an analog signal available through a BNC connector at the back of the detector housing. Since the signal is analog, an optional 12-bit and 16-bit data acquisition system and software is available to digitize its output into a computer. A DC power supply for this detector (sold separately) is also required. This detector is designed for use with scanning monochromators to capture the intensity of one wavelength at a time. An optional mount allows it to mate to any Sciencetech scanning monochromators. Sciencetech can also provide an optional custom mount for mating to non-Sciencetech monochromators and spectrographs.

The Sciencetech PMH-01 Photon Counting Module is self-contained compact unit incorporating PMT tube, high-speed amplifier, discriminator, and high voltage power supply. The output signal (train of pulses, the number of which corresponds to the number of detected photons) can be sent via a BNC connector, to an external counting/displaying circuit. The PMH-01 outputs digital signal (pulses) only. There is no analog output port.

The photon counting head used has low power consumption (max 0.5W). It is already adjusted for best S/N ratio. There is no additional adjustment necessary to start the operation.

This single element detector is effective at sensing wavelengths between 2,000nm and 12,000nm. 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, a supply of liquid nitrogren is required. As with most IR detectors, MCT detectors are coupled to AC preamplifiers which means they detect only 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).
This MCT detector includes a preamplier. This system also requires a power supply (sold separately, compatible with 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
