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.

The Sciencetech variable focus assembly is coupled to the output port of Model 201-1K arc lamp housing for refocusing its collimated light into a divergent spot. An adjustable lever is used to move the 4 lens assembly along the optical axis. The output beam can be refocused at any f number from infinity (collimated) to f/2. This feature can be used as an intensity controller as the light can be concentrated to any size spot larger or smaller than the 2" diameter of the output port.

To adjust the focus simply use the handles provided to slide the lens tube in or out of the lamp housing. Note that the lens tube has approximately 1” of travel. Stoppers on either end of the lens tube prevent the lens tube from contacting the lamp or from being pulled out of the lamp house.

This assembly uses UV-Fused Silica lenses for optimal UV light transmission.

This is a high resolution slit designed to have 10 um resolution. The slits are manufactured from stainless steel to maximize mechanical accuracy. The height of the SS-84 slit can also be adjusted between 0-10 mm, 10-20 mm and 20-30 mm through built-in manual curtain sliders.

Please note that these slits are not designed to maximize throughput for extremely high resolution monochromators, due to the straight orientation of the slits. For maximum resolution, the slits need to be designed on a curve that corresponds to the curvature of the point of least confusion. However, this is only a significant factor for systems with optical pathlengths of 1m and greater. Please speak with your authorized Sciencetech technical sales staff member if you need maximum resolution for a long pathlength system.

This standard optical liquid filter is equipped with BK7 windows (350 to 2000 nm). Can be operated either horizontally or vertically but horizontal operation is preferable due to potential risk of air gap in the light path. Stainless steel provides superior corrosion resistance compared to aluminum for corrosive liquids.

$ 2,199.00

This standard optical liquid filter is equipped with fused quartz windows (270 to 2500 nm) which transmit UV light. This allows it to be used for UV applications. Can be operated either horizontally or vertically but horizontal operation is preferable due to potential risk of air gap in the light path. Stainless steel provides superior corrosion resistance compared to aluminum for corrosive liquids.

The Sciencetech Polarizing variable frequency optical chopper is used with the detectors during Martin-Puplett mode. The chopper is positioned in front of the output port, and captures the output at 45 degrees from the two planes of polarization. This facilitates the retrieval of the Fourier Transform Interferogram during M-P mode. The chopper itself is designed for high stability and a broad range of frequency control (from 0.5Hz to 100Hz). The price includes the servo motor and software controller.
