Latest Patents

Kenji Maebara holds a patent for a focus optical system and optical disc master exposure apparatus. This invention involves adjusting the relative positional relationship between a cylindrical lens and a 4-division detector in an astigmatic optical system. The goal is to ensure that an interference fringe appearing in reflected light from an optical disc master is directed to a dead zone of the 4-division detector. This adjustment allows for an astigmatic focus servo that is unaffected by variations in the focus error signal caused by the interference fringe. Consequently, the effects of the interference fringe in the reflected light from an optical disc or optical disc master can be effectively suppressed.
