Latest Patents
Iijima's latest patents include an innovative optical defect inspection apparatus. This apparatus utilizes a laser beam that is oscillated from a laser source and is directed through first and second plane mirrors before entering a beam expander. The design addresses the issue of surface deterioration on the mirrors caused by laser illumination, which reduces reflectance. To maintain the light quantity entering the beam expander above a reference value, the apparatus features a mechanism that rotates and/or translates the reflecting surfaces of the mirrors while keeping the optical axis unchanged. This advancement prolongs the useful life of the mirrors without displacing the optical axis.
