Description
The 9863/350B is a high-performance photomultiplier designed for advanced photon detection applications. With a 51mm (2”) diameter, this device features an infra-red sensitive S20 photocathode, which has been electrostatically reduced to a 9mm diameter. This design, combined with 14 BeCu dynodes of linear focused construction, ensures fast timing and extended linearity, making it an ideal choice for precision-demanding tasks.
This photomultiplier is particularly noted for its high gain and fast time response, attributes that are critical for applications requiring rapid data acquisition and processing. Its low dark count rate and minimal afterpulse rate further enhance its suitability for time-correlated studies, ensuring that measurements are both accurate and reliable. The device operates efficiently across a spectral range of 290 to 850 nm, supported by a borosilicate window with a refractive index of 1.49, ensuring optimal performance in various light conditions.
The 9863/350B's robust construction and advanced features make it a versatile tool for numerous applications, including LIDAR, particle counting, and general photon counting tasks. Its compact size and lightweight design, weighing just 190 grams, facilitate easy integration into existing systems. This photomultiplier is engineered to meet demanding operational requirements while maintaining precision and reliability, making it a valuable asset in scientific and industrial settings.
