Photon counting systems can be supplied complete with pre-selected photomultipliers for immediate use, or in modular format for integrating with existing hardware and electronics.
The PDM9107-CP-TTL is a cylindrical format photon counting module incorporating a high sensitivity, low noise, 29mm diameter photomultiplier, a fast amplifier-discriminator, and a low power high-voltage supply. The combination of high-speed electronics and fast photomultiplier with low dark counts enables a wide dynamic range to be achieved.A positive polarity high-voltage supply is used for maximum count rate stability at very low light levels and the spectral range is 280-630nm.
The TTL oputput of the PDM9107-CP-TTL is fully compatible with the MCS-CT3 multi-channel scaler/counter timer module for use in photon counting applications with a very wide dynamic range. The photomultiplier high-voltage and discriminator threshold level are pre-set for optimum performance, enabling photon counting operation simply by connecting to a +5V supply (which can be derived from the MCS-CT3).
