Abstract
The hybrid micro-objective lens with the kinoform corrector has been developed and fabricated. Kinoform corrector is made by the photorastering technology. The numerical aperture of the micro-objective is 0.6 and 0.7; the focal length is 9.1 and 5.9 mm. The micro- objective can find its applications for various laser interferometers to collimate radiation of diode lasers and for date recording and read-out optical and magneto-optical disks.
