HOPG Analyzing Crystal
Pyrolytic graphite (HOPG) is a new type of high-purity carbon material, produced by treating pyrolytic graphite under high temperature and high pressure. Its properties are close to those of single-crystal graphite, and it is commonly used as a monochromator and focusing optical component for X-rays and neutrons.
Introduction
Highly Oriented Pyrolytic Graphite (HOPG) HOPG is a new type of high-purity carbon material, produced by treating pyrolytic graphite under high temperature and high pressure. Its properties are close to those of single-crystal graphite, and it is often used as a monochromator and focusing optical component for X-rays and neutrons.
Specifications
Available flat and cylindrically bent HOPG crystals:
| Grade | Mosaic spread / mosaic angle | Typical thickness | Minimum size | Maximum size |
| AGraphZ | 0.4±0.1° | 2（-1）mm | 10 mm x 10 mm | 30 mm x 20 mm |
| AGraphY | 0.8±0.2° | 2（-1）mm | 10 mm x 10 mm | 50 mm x 50 mm |
| AGraphZ | 1.7±0.4° | 2（-1）mm | 10 mm x 10 mm | 50 mm x 50 mm |
| AGraphZ | 3.5±1.5° | 2（-1）mm | 10 mm x 10 mm | 50 mm x 50 mm |
| single-bent HOPG*R=450, 220, 145 mm | 0.4±0.1° | 2（-1）mm | 10 mm x 10 mm | 50 mm x 50 mm |
*In addition to single-bent HOPG, double-bent HOPG is also available, including large-curvature cylindrical, conical, spherical, toroidal, and parabolic shapes.
