Graphite-Monochromator 151


The graphite monochromator 151 contains a highly oriented pyrolytic graphite crystal (HOPG) mounted in a compact metal housing.

Inside the radiation-proof housing the crystal can be manually adjusted to the ideal Bragg angle for the used X-ray wave length. The diffracted beam is made directly visible by a fluorescent screen on a small lead glass window.

Adjustable entry and exit slits ensure a precise limitation of the X-ray beam path. A wide variety of adaptor plates is available for the mounting of the monochromator on the tube hoods of all standard manufacturers.
