The PHOTONIS QUANTUM™ Sub-Miniature Advanced Performance Detector offers previously unobtainable levels of
amplification, dynamic range, and detection sensitivity in an ultra compact, easy to use package. It is specifically designed for
miniature sensors and hand held analytical instruments, such as mass spectrometers, Residual Gas Analyzers, VUV spectrometers,
and leak detectors.
The leading edge design of the QUANTUM™ detector allows operation up to 100°C and non-operational vacuum baking to 300°C.
The high temperature capability of the QUANTUM™ can result in shorter chamber degassing cycles and ultra quiet instrument
operation.
The QUANTUM™ detector utilizes Long-Life™ Microchannel Plates (MCPs). PHOTONIS exclusive Long-Life™ microchannel plates
are the highest performing MCPs available. High channel density and Extended Dynamic Range™ (EDR) MCPs provide dynamic
range improvements of up to ten times that of conventional microchannel plates.
These MCPs also give the new QUANTUM™ sub-miniature detector superior sensitivity in the smallest package available. This
compact assembly provides for easy installation. The flat input surface provides uniform ion conversion and the higher aspect ratio of
the MCPs provides gains in excess of 10,000.
