CHELMSFORD, Mass. — McPherson Inc. offers the 671MX amplifier, a high-vacuum-compatible, current-to-voltage converting device developed for use with vacuum UV silicon photodiodes.
With an integral socketed photodiode mount, the combination detector/amplifier hybrid can be used to measure small photogenerated currents with resolutions of 10 fA and dynamic ranges of four orders of magnitude. The device consists of a very low noise operation amplifier with selectable feedback resistor. The feedback resistor is socketed and may be changed to match gain and dynamic range requirements.
All amplifier components are low-tolerance, resulting in consistent current-to-voltage transfer characteristics with minimal offset voltage. The amplifier is produced on a vacuum-compatible ceramic board and uses all vacuum-compatible components.
