  • McPherson - Model 642 - Soft X-ray Solid Anode Electron Impact Source

    McPherson - Model 642 - Soft X-ray Solid Anode Electron Impact Source

    The Model 642 soft x-ray source is a compact, convenient to operate source for the 2keV to 50eV region. The unique dual-output of equivalent beams make it a useful source for many comparative applications in addition to wavelength calibration and so on. The two output beams originate from two views of the single emitting spot where the electron beam from the single hairpin filament collides with the interchangeable anode. The emitting spot is about...

  • McPherson - Model 629 - Windowless Hollow Cathode Source

    McPherson - Model 629 - Windowless Hollow Cathode Source

    The Model 629 Hollow Cathode is a CW gas discharge source used to ionize molecular or rare gases. It operates with no window and is a rich source of ion lines at wavelengths longer than 25 nm (less than 50 eV). Output line emission depends on the gases used. It is possible to mix or switch gases during operation. It is electrically quiet and features a water cooled anode and cathode. A differential pumping accessory is available to limit the gas...

  • McPherson - Model 634 - Deuterium Source with Magnesium Fluoride Window

    McPherson - Model 634 - Deuterium Source with Magnesium Fluoride Window

    The Model 634 Deuterium lamp features a Magnesium Fluoride window, 1mm diameter emitting plasma and ~f/6 output. The source system includes cables, lamp housing and a power supply for lamp operation. This source is useful for vacuum ultraviolet (UV) and deep UV operation. Output between 380 and 165nm is continuous; below 165nm, molecular lines predominate. Because the sealing window is polished Magnesium Fluoride, cut with its optical axis...

  • McPherson - Model 625 - Mercury Calibration Source

    McPherson - Model 625 - Mercury Calibration Source

    Mercury calibration lamps are small, rugged, and easy to use. Because the lamps operate at low pressure, well spaced, intrinsically narrow and bright Mercury emission lines dominate the output spectrum. Background between the lines is very low. The output wavelengths are known...

  • McPherson - Model 621 - Universal Chimney-Style Lamp Housing

    McPherson - Model 621 - Universal Chimney-Style Lamp Housing

    The Model 621 modular light source operates with a variety of light sources: tungsten, Xenon and IR emitters. It is a complete system with forced air cooling, lamp mount module, housing, condenser, power supply and cables. The Model 621 mounts directly on the 5-inch diameter entrance slit of any McPherson spectrometer and may be adapted to other spectrometers or for standalone operation.
