Features:
The ellipsoidal monochromator FOCUS 500 operates according to Bragg´s Law of X-ray diffraction. A single wavelength of X-rays is reflected from a quartz single crystal mirror at a specific angle of reflection. The FOCUS 500 utilizes an ellipsoidal X-ray mirror. An ellipsoidal mirror images a point source located at the ellipsoidal mirror’s focus on the sample perfectly. The mirror has a 500 mm Rowland circle diameter which offers a high X-ray energy dispersion. the large surface area of the quartz crystals defines a solid angle fo Y-ray diffraction and hence leads to an intense X-ray flux from the monochromator for high efficiency.
The X-ray source XR 50 M is specially designed for use with the monochromator. Due to the small source size in the focusing mode the monochromator resolution is limited by the rocking curve width of the quartz crystals (160 meV) only. |
