Description
The 9893/350B is a sophisticated 51 mm (2") diameter photomultiplier, designed to deliver exceptional performance in a variety of photon detection applications. This model features an end window configuration with a blue-green sensitive photocathode, optimized for enhanced sensitivity and precision. The photocathode is electrostatically reduced to a 9 mm active diameter, which, combined with the 14 BeCu dynodes of a linear focused design, ensures fast timing and extended linearity in demanding environments.
Engineered for superior quantum efficiency, the 9893/350B operates effectively across a spectral range of 290-630 nm, where the quantum efficiency exceeds 1% of its peak value. The photomultiplier's construction includes a borosilicate window with a refractive index of 1.49, contributing to its robust performance in various light detection scenarios. With a peak quantum efficiency of 25% and a luminous sensitivity of 60 µA/lm, this device is ideal for applications requiring high gain and low noise, such as LIDAR, particle counting, and general photon counting tasks.
In addition to its high sensitivity, the 9893/350B offers a low dark count rate and a minimal afterpulse rate, making it suitable for time-correlated studies. The device's fast time response is characterized by a single electron rise time of 2 ns and a single electron full-width at half maximum (FWHM) of 3 ns. These specifications, coupled with a low dark current and excellent linearity, ensure the 9893/350B delivers reliable and consistent results across a range of operating conditions.
This photomultiplier is designed to withstand rigorous conditions, with a maximum rated anode sensitivity of 1000 A/lm and a nominal anode sensitivity of 5000 A/lm. It operates efficiently at an overall voltage of 2700 V for nominal sensitivity and 2300 V for maximum rated sensitivity, ensuring adaptability to various experimental setups. With a weight of 190 g, the 9893/350B is a compact yet powerful solution for advanced photon detection needs.
