Description
**Product Overview: 9924B Series Photomultiplier** The 9924B series photomultiplier is a state-of-the-art device designed for high precision and reliability in light detection applications. With a 29 mm (1.13”) diameter end window, this photomultiplier is engineered to offer superior performance in various scientific and industrial settings. It features an enhanced green-sensitive bialkali photocathode, which ensures high quantum efficiency and excellent sensitivity across a broad spectral range. The device is equipped with 11 high gain, high stability SbCs dynodes of box and grid design, providing robust signal amplification capabilities.
This photomultiplier is ideal for situations requiring precise light measurement, such as x-ray and gamma-ray spectroscopy, and photon counting of bio- and chemi-luminescent samples. The 9924B series is designed to operate at low voltages, making it energy efficient while maintaining high gain and low noise performance. The photomultiplier's dark current and dark count rate are optimized for minimal interference, ensuring that the measurements remain accurate and reliable even in low light conditions.
The 9924B series also includes a variant, the 9924QB, which is specifically tailored for applications needing UV sensitivity. Both models are constructed with high-quality materials, including borosilicate and fused silica, which contribute to their durability and performance under various environmental conditions. The photomultiplier's compact design, combined with its advanced technical features, makes it a versatile choice for researchers and engineers seeking dependable light detection solutions.
