Potassium hydrogen phthalate (KAP)

Potassium Hydrogen Phthalate (KAP) is a monoclinic organic crystal material with excellent mechanical properties and is easy to cut and grind. It is stable at room temperature, has good tolerance to many organic solvents, excellent thermal stability, and high solubility in water.

KAP crystals have excellent electro-optical and nonlinear optical properties, with high nonlinear optical coefficients and a wide transparency range, which makes them widely used in fields such as laser frequency conversion and optical modulation.

KAP crystal is also a commonly used X-ray diffraction standard crystal, which plays a key role in the calibration process of X-ray diffractometers and is commonly used to study the X-ray diffraction characteristics of other materials. KAP crystals are widely used in X-ray monochromators for effectively focusing X-ray emissions due to their excellent X-ray diffraction ability and stable structure. By bending the crystal plane in two directions to form a circular surface, it is possible to focus in the sagittal and tangential directions with minimal aberration. The applications of these components include high-energy resolution analyzers for synchrotron beamlines, analytical chemistry instruments, spectroscopy and imaging of thermally dense plasmas - most commonly used for target diagnostics in nuclear fusion research facilities.

DHD technology provides high-quality KAP crystal materials and corresponding X-ray diffraction monochromator components customized in various specifications.
