McPherson has launched a 310STS tunable source system. The model has efficient grazing incidence optics with light sources that work between 1nm and 120nm. Sources include electron impact solid anode type for SXR and a windowless hollow cathode for lower EUV energies, which can fit to the scanning entrance slit of a one metre focal length grazing incidence monochromator. The monochromator has adjustable apertures, accepts multiple diffraction gratings and has a motor drive controlled by PC. The selected wavelength travels directly to devices under test. Sample motion is required only as analysis requires.
The system is suited to test spatial response of x-ray cameras, calibrate detectors, and spectrally test photocathodes. Thin-film reflectance, filter transmittance and absorbance are also possible. It can be used for integration to existing experimental test chambers, or as a complete system with McPherson sample handling or chambers. Furthermore, it is a system for both SXR and EUV spectrophotometry.
