Light Sources

Our XUV-VUV-UV-VIS-IR Sources and Power Supplies are universally useful and fit McPherson Monochromators/Spectrometers and other systems. They function as stand alone units, have low f/numbers, and feature efficient reflective and refractive optics. Suitable source accessories complement spectral regions and meet given requirements as differential pumping for the XUV-VUV or N flushing for IR.

We stand ready to use our experience to help with selecting or designing suitable spectral illuminators and instruments for analytical spectrometry.

• Model 642 - Soft x-ray source, useful in the 1-100A region - A stable and reproducible source of K-band lines. This source operates on the principle of electron bombardment of an anode. Various anodes are available; boron, carbon, magnesium, oxygen, aluminum and nitrogen, for example.
• Model 642-1 - Soft x-ray source, same as above but with an in vacuo indexable turret allowing use of six types of anodes. Also on this source are two indexable four position filter holders.
• Model 634 - Penning type continuous gas discharge source for use in the 50 - 1850 Angstrom range. This unit utilizes an intense magnetic field to confine the electrons emitted by the selectable cathode. This approach condenses the excitation of the source gas and the ionized material sputtering from the cathode. Emission lines are produced depending on the combination of discharge gas and cathode material.
• Model 628 - Capillary discharge source, when operated with hydrogen, provides a continuum from 850 Angstroms to the visible portion of the spectrum. Operated with He, Ne, or Ar extremely monochromatic resonance lines are available below 1500 Angstroms. Designed to operate with a continuous gas flow, windowless. May require differential pumping and Model 730 power supply.
• Model 629 - Hollow cathode lamp - windows for operation above the vacuum range are available as accessories. For windowless operation the unit includes mounting flange with actuator knob for moving a seal bushing to limit leak to slit of spectrometers. May require differential pumping and Model 730 power supply.
• Model 630 - Hinteregger discharge lamp for production of noble gas spectra, provides line spectra or continuum depending on gas, pressure and type of excitation used, includes mounting flange; has same slit seal feature to reduce leakage as Model 629. May require differential pumping and Model 730 power supply.
• Model 631 - Hollow cathode (calibrated) similar to the other discharge sources described but available as a certified irradiance standard. This lamp is manufactured in Germany and at request can be supplied as a calibrated source per the BESSY facility in Berlin. Differential pumping and ultra-stable power supply is required.
• Model 632 - Deuterium source for vacuum ultra violet and ultraviolet, does not require a flow of gas, vacuum pumps or coolant. Offers a continuum ranging from 1150 - 3700 Angstroms. Includes power supply.
• Model 626 - Mercury pen ray calibration lamp, with power supply, vacuum version.
• Model 625 - Mercury pen ray calibration lamp, with power supply, atmospheric version Note: Zn, Ca and other pen rays are also available.
• Model 619 - Tungsten calibrated lamp with calibrated power supply, certified for spectral irradiance.
• Model 616-5 - Xenon (150W) or Xenon-Mercury (200W) short arc source, consists of air cooled lamp unit and variable power supply. Reference monochromator for F/No. matching. Available with quartz lens or for use with the Model 617 first surface focusing system.
• Model 616-4 - Deuterium (30W), convection cooled lamp and power supply. Reference monochromator for F/No. matching. Available with quartz optics or for use with the Model 617 first surface focusing system.
• Model 621 - Lamp house and source system is universal. Through the use of standard accessories and socket adapters a variety of sources can be used safely and effectively within this single housing design.
• Model 618 - Tungsten Halogen light source is a high energy unit (f/2) with a 100 W lamp. This source produces an intense continuum from 400 nm to 2 microns. With its compact, forced air cooled housing, and UV grade lens focusing assembly, it is the perfect unit for use in high intensity illumination and spectrometry applications.
• Model 616-1 - Glowbar, silicon carbide element with line operated variable power supply. Two versions available: stand alone with germanium optics or for use with the Model 617 focusing system.
• Model 613 - Xenon (75W) or Xenon Mercury (100W) arc source, lamp unit contains a first surface condensing focusing mirror, requires Model 713 power supply.
• Model 610 - Tungsten Halogen (650W), consists of lamp unit, line operated power supply and first surface condensing focusing mirror, compact unit, ready to mount on McPherson or other standard slit assemblies.

• Model 713 - D. C. power supply for use with housing Model 613. Operates both Xenon and Xenon Mercury for 75 and 100 watt arc sources. Self-starting, highly stable and line operated from 110V/60Hz or 220V/50Hz sources.
• Model 718 - Power supply is a highly regulated, adjustable DC power source for use in spectroscopy. Capable of powering tungsten-halogen, ceramic element and infrared emitter type light sources, this supply is flexible and extremely stable.
• Model 750-03 - D. C. power supply for 150 watt Xenon and 200 watt Xenon Mercury short arc lamps, self-starting, highly stable, line operated 110V/60Hz or 220V/50Hz.
• Model 750-04 - Universal D. C. power supply for use with Tungsten, Tungsten Halogen or glowbar sources up to 100 watts. Highly stable and line operated from 110V/60Hz or 220V/50Hz sources.
• Model 730 - Power supply for use with rare gas discharge lamps as the Hollow Cathode Model 629 and the Hinteregger Model 630, 2000V, 0.5amp constant current. Installed in a fan cooled bench top 19 inch cabinet, safety interlocked, operates from 110V/60Hz or 220V/50Hz.
• Model 748 - Power supply (FLA-748), use with Zn, Ca, and Hg calibration sources. A highly stable pen-ray lamp power supply. Features simple on/off control and lamp select switch, operates from 110V/60Hz or 220V/50Hz.
