Title: Optical pickup
Inventor: KATO MASAYUKI
IPC: G02B27/28
Filed: 1986-02-25
Abstract: PURPOSE:To improve the efficiency of an optical system and to reduce the weight, size and cost of the optical system by constituting the optical system of various holograms or the like and making an incident angle on the optical axis of these holograms almost coincide with an outgoing angle. CONSTITUTION:The optical system is constituted of an off-axis type optical system consisting of a hologram lens 21 for collimation, a surface releaf type hologram 22, a lambda/4 plate 23, and an objective hologram lens 24 and the incident and outgoing angles on the optical axis of the lenses 21, 24 are equally formed as beta. Since the inclined angle of interference stripes formed on the hologram lenses is almost zero when the hologram lenses are formed so that the incident and outgoing angles are equal, the inclined angle is not almost changed even if the film thickness is changed by expansion or contraction at the time of developing processing. Consequently, the incident and outgoing angles beta make it possible to obtain always the maximum efficiency, so that highly efficient holograms can be formed and high efficiency can be obtained also as the whole optical system.
