Description
The PDM USB series photodetector module is a cutting-edge solution designed for precision and versatility in photon detection. Available in both cylindrical and rectangular formats, these modules offer a choice between 25mm and 30mm diameter photomultiplier tubes (PMTs). This flexibility allows users to tailor the module to their specific requirements, ensuring optimal performance in various applications.
One of the standout features of the PDM USB series is its advanced dynamic range capabilities. The module incorporates dead time correction to address non-linearity at high count rates, a common issue in photon detection due to pulse pile-up. By applying the correction formula, N = n/(1-nT), where N is the true count rate, n is the measured count rate, and T is the count rate correction factor, users can achieve a deviation from linearity typically within +5% at 100 Mcps. This ensures accurate and reliable data even in high-intensity scenarios.
The PDM USB modules are equipped with user-friendly software, providing the ability to select operating voltage and set threshold levels as needed. The modules support three software-configurable counting modes: pre-set number of channels, pre-set total measurement period, or continuous operation. This versatility makes the PDM USB series suitable for a wide range of experimental setups. Additionally, the modules can be conveniently powered through the USB connector, eliminating the need for an external power supply and enhancing ease of use.
Designed with practicality in mind, these modules offer easy plug-and-play operation and feature magnetic and electrostatic shielding to protect against interference. Furthermore, the option for fibre coupling enhances the module's adaptability, allowing integration into complex optical setups. With low noise performance and multiple spectral range options, the PDM USB series photodetector modules are an excellent choice for researchers and engineers seeking reliable and flexible photon detection solutions.
