An integrated optical pickup system for reproducing an information signal stored on a recording surface of an optical disk is comprised of a first optical glass substrate, integrated with a semiconductor laser, a reflection collimating lens, a transmission off axis diffractive object lens and a reflection layer, for impinging a converged light beam onto the optical disk and collimating the converged light beam after being reflected from the recording surface and a second glass substrate, integrated therein with a twin focusing beam splitter and a photo detector, for guiding the collimated light beam from the first glass substrate to the photo detector, thereby allowing the integrated optical pickup system to reproduce the information signal off the recording surface of the optical disk. <IMAGE> |
