Low stress magnesium fluoride(MgF2) bar
Grain boundary stress is the stress acting on the grain boundary. On the grain boundary surface, the atomic arrangement transitions from one orientation to another, so the atomic arrangement at the grain boundary is in a transition state. The contact interface between the grain and the grain is called the grain boundary. Low stress magnesium fluoride refers to the maximum stress less than 15NM for magnesium fluoride with length greater than 40mm or less than 3NM for 2mm thickness. The low stress is directly related to the crystal growth process, annealing process, and post-processing and treatment.
Magnesium fluoride(MgF2) excimer laser material
Magnesium fluoride is widely used in excimer lasers of argon fluoride, krypton fluoride and xenon chloride because of its high transmission rate, long service life and low light energy loss. Theoretically and experimentally, it is proved that the more ultraviolet wavelength lasers have higher material requirements, which means that the magnesium fluoride materials used in these three wavelength lasers can be different. As the world’s leading supplier of magnesium fluoride crystals, we have a good understanding of the material requirements for excimer lasers at different wavelengths.
Magnesium fluoride(MgF2) 121nm Material
The extreme ultraviolet magnesium fluoride material must be high purity material, and the crystal growth process must be controlled by atmosphere to obtain higher transmittance, and because of the complexity of the photoion welding process, the crystal orientation, microstructure, lens processing and annealing requirements are extremely demanding. We are currently the world’s leading supplier of this product, specializing not only in materials but also in applications.
Magnesium fluoride(MgF2) single crystal material
Magnesium fluoride is a tetragonal crystal system, characterized by each anisotropy. So it must be considered as single crystal in precision imaging and signal transmission.
The main dissociation plane of magnesium fluoride is 110, but the smallest birefringence is 001 plane. Single crystal means the direction is random, it may be 110,100,001 or other direction; this varies a lot in practical application. If the customer does not specify the direction, the intrinsic crystals are processed according to the direction.
UV barium fluoride
The barium fluoride products applied in the UV band require no obvious absorption in the range of 200-400NM, and the crystal structure can be single crystal or polycrystalline. The UV barium fluoride obtained is often related to the raw material, crystal growth preparation and crystal doping, but the finished crystals should meet ROHS & REACH requirements.
Low stress low delay barium fluoride
The phase delay caused by the deflection of the phase of light through a diphasic or multidirectional material is called phase delay; barium fluoride materials are tetragonal and isotropic, but there are still subtle differences in different directions, so a lower phase delay is required to obtain an accurate monitoring signal. The specific material and processing of intrinsic crystals can guarantee your isotropic requirements
