Lithium fluoride chipping problem?
Lithium fluoride crystalline materials are extremely difficult to process because of their hydrophilic nature. Also because of the crystal orientation, it leads to breakage along the main dissociation under external force. Therefore, the processed lenses are mostly with many blanks, which cannot be solved with the current process. If the requirements for chipping are too strict, it will lead to a large production defect rate, which in turn will push up the product price.
