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 sample chamber has one input port and two output ports. One of the output ports is 90° relative to the input port, allowing it to be used in fluorescence-type applications. The other output port is directly across from the input port, allowing it to be used for transmission measurements/applications. The lid of the sample chamber can be removed, exposing the built-in cuvette holder inside. This cuvette holder holds 10 × 10mm cuvettes. Optionally, the cuvette holder can be upgraded to a thin film holder capable of mounting 20 × 20mm samples. We recommend talking with one of Sciencetech's technical sales staff to determine if the thin film holder will be sufficient for your particular application. The sample chamber dimensions are 205 × 128 × 154mm (8"× 5"× 6").

Please note that this sample chamber does not include any built-in optics for focusing and defocusing light onto the sample, as the light beam through the chamber is anticipated to be collimated. Such focusing and defocusing optics are part of the optical coupling tubes that connect the sample chamber to various external components, such as to a light source or monochromator.

This 12-bit data aquisition module features 3 analog inputs via BNC connectors. The data aquisition board is 12Bit and can measure a single channel up to 50Ks/S. An additional BNC connector for a trigger input can be used to time measurements and/or send signals to external hardware such as a high speed shutter.

This module includes 1 BNC cable and 1 USB cable so that it is ready to interface with a single channel detector such as a PMT or UVSi photodiode detector (sold seperatley). For spectroscopy systems the Sci-Spec Windows application software to interface with a Windows Based PC is required and is sold separately.

This module is wired for single ended input for +/-10V input range. This module can be wired for differential inputs upon request.
For most single channel data aquisition options where differential inputs are not required the SCI-DAS-12USB-LS option is a suitable and economical option.

multi-channel dataaquisition is possible using SciSpec software, if this option is required please speak to a Sciencetech technical sales representative.
