WSZ-5A Single Photon Counting Experimental System
Product details
|
The WSZ-5A single photon counting experimental system is a set of experimental systems developed by our company. The experiment consists of a single photon counter, an external optical path of the refrigeration system, and other components. The signal processing part of the system uses pulse height discrimination, and the filtered signal is sent to a pulse counter for counting. The output signal is also directly led to the panel, and the experimenter can expand the experiment according to their own experimental situation, which gives the experimenter a larger experimental space to achieve the purpose of learning and exercise. Single photon counting experimental systemcharacteristic: ·By using USB to communicate with computers, experiments can be easily conducted with simple operation and clear results. ·A stable pulse counter with advantages such as wide counting range and accurate counting is applied. ·Using CR110 photomultiplier tubes for reception and utilizing semiconductor refrigeration technology to reduce the instrument's dark count ·The instrument is equipped with dimming film, filter, and adjustable guide rail ·It is convenient to expand experiments, and experiments can be expanded in experimental mode. Main technical specifications of the single photon counting experimental system: Spectral collection range:380-650nm Integral time:Number adjustable Discrimination level:Number adjustable High voltage control:Number adjustable The largest number:107 Dark count:≤30CPS-20°C |
