Mepsicron-II tm Series Single-Photon Imaging
Detector System
MODEL 2601B TECHNICAL DESCRIPTION, OCT 2001
General Description
The Model 2601B Mepsicron-II-tm Single-Photon Imaging Detector System is a high-performance, ultra-low-light-level digital electronic camera /optical detector system. It is designed for demanding, ultra-low-light scientific imaging and spectroscopy applications in the spectral range from below 180 nm to beyond 900 nm.
This detector combines the most desirable features of two fundamentally different types of traditional optical detectors into one system. The Mepsicron-II offers the exceptional ultra-low-light sensitivity, signal-to-noise ratio and time-resolved capabilities of a digital, single-photon-counting photomultiplier (PMT) combined with the full X-Y position-sensitivity of a 1-D or 2-D array detector. Although simpler in practice, the system effectively operates much like a 23 mm diameter array of more than 125,000 microscopic (50 x 50 micron) single-photon-counting PMT's, each capable of detecting single photons with an extremely high signal-to-noise ratio. Spectra and images are created by digitally summing successive single-photon digital events.
These unique and powerful capabilities have resulted in the Mepsicron-IItm system being successfully used worldwide in a range of specialized applications in physical, chemical and biological science where improved ultra-low-light or time-resolved performance is required compared to more conventional detectors such as CCD's or single-channel (non-imaging) PMT's.
Examples of typical applications are:
- Raman multichannel spectroscopy and imaging
- Fluorescence and luminescence spectroscopy/imaging
- Optical emission microscopy for microelectronics
- Astronomy and space science
- X-ray and neutron imaging with fiber optics/scintillators
- Biological and medical imaging
- Single-photon time-resolved spectroscopy/imaging
Similar UHV-vacuum-compatible systems are also available from Quantar Technology for direct detection and imaging of single atomic charged-particles (electrons, positrons, ions) and extreme-UV and soft X-ray photons in vacuum environments.
