WAVELENGTH PLATE APPLYING ULTRAVIOLET RAYS

摘要

PROBLEM TO BE SOLVED: To form a wavelength plate for an ultraviolet region whose work errors are mitigated and whose wavelength dependency is low. SOLUTION: The wavelength plate is formed by using lithium fluoride calcium aluminum (fluoride material) to which Mg or Be is added and whose double refractive index is small such as 10-3.
