PHOTONIS Introduces a New High Quantum Efficiency Photocathode
New Hi-QE Photocathode increases QE 50% over S20 types.
2 Feb 2016PHOTONIS Netherlands, a leading electro-optic component manufacturer, announced the release of a new photocathode designed to provide a unique combination of extremely low dark counts, fast response time, and a high quantum efficiency.
Hi-QE Photocathodes are engineered to provide heightened spectral sensitivity in specific wavelength ranges for use in photon-starved applications.
The Hi-QE Photocathode increases quantum efficiency (QE) 50% when compared to standard S20 photocathodes, while lowering dark counts as much as 10X with near-symmetrical pulse height distribution. Currently the spectral ranges cover UV, Blue and Green wavelengths.
The new photocathodes are offered as an option to a number of PHOTONIS photon counting products, including the hybrid photo diode, image intensifier, and MCP-PMT families of detectors. The Hi-QE option can also be specified for the Imaging Photon Camera, which provides high spatial resolution.
PHOTONIS’ new Hi-QE Photocathode is ideal for use in extremely low light level applications, including astronomy, biology, fluorescence, plasma research or nuclear physics. Additionally, the combination of detection efficiency, speed and low signal-to-noise ratio enhances the capabilities in single photon counting applications.
