McPherson offers Detectors and Detection Systems for the Ultraviolet, Visible and Infrared region as well as the Vacuum Ultraviolet. These all work with McPherson spectrometers. Accessories are available to adapt them for many purposes.
UV Visible and Infrared
Model 654 Photomultiplier Tube housing for 28mm diameter side view PM tubes. Use with 7640 HV supply.
Model 663-2 Silicon Photodiode for 200 to 1100 nm region
CCD Detectors - McPherson works with most commercial CCDs. Order upgrades for legacy instruments or call to consult.
Solid State Infrared Detectors
* Silicon/Indium Gallium Arsenide (Si/InGaAs) Two Color Detectors consist of 2 active elements, each with a different spectral response, mounted in a coaxial configuration.
Vacuum Ultraviolet and Deep UV
Model 650 52mm end on Photomultiplier housing, works from 30 to 900nm with PMT and scintillator. Use with 7640 HV supply.
Model 650-1, a PMT housing with front flange seal for MgF2 window and solar blind PMTs.
Model 658 28mm end on Photomultiplier housing. Most sensitive combination end-on photomultiplier with scintillator. Use with 7640 HV supply.
VUV Silicon Diode Silicon photodiode for extreme and vacuum UV ~1 to 1000nm. Also available with UHV packaging, amplifier and NIST traceable calibrated response.
Model 422 rotatable Photodiode mount. Moves Si photodiode into and out of beam for in situ calibration. Also available for UHV.
Model 452 Polarization Analyzer with photodiode. Measures reflectance of a 45-degree Gold coated mirror and rotates through 90-degrees.
Extreme UV and Soft X-ray
Open microchannel plate (MCP) intensifier for 1 to 180nm select plate (single, high gain, chevron, etc.) photocathode and phosphor. Available gated. McPherson offers purpose built MCP assemblies as well as packaged systems. Uses Model 735 HV supply.
Model 425 Channel Electron Multiplier (CEM) for photon counting or CW detection from 1 to 180nm. Use with 7640 HV supply.
Detector Power SuppliesModel 7640 high voltage (HV) adjustable DC supply, extremely stable. With 1, 2 or 5kV output.
Model 735 operates single stage or chevron MCP intensifiers. High voltage to the MCP screen and channel ands low voltage for operation in positive channel mode.
