    摘要: An optical reproduction system, which can be configured for example as a catadioptric projection lens. This system includes an optical axis and a first deflection mirror, which is tilted in relation to the optical axis at a given tilt angle. One of the deflection mirrors has a ratio Rsp of the reflection coefficient Rs for s-polarised light to the reflection coefficient Rp for p-polarised light, in an incidence angle range that includes the tilt angle, of greater than one, whereas the corresponding ratio for the other deflection mirror is less than one. The deflection mirrors thus ensure that the polarization-dependant influence of the travel light remains minimal.

    摘要: An optical component and a coating system for coating substrates for optical components with essentially rotationally symmetric coatings, the system having a planetary-drive system (1) that has a rotating planet carrier (2) and several planets (4), each of which carries a single substrate, that corotate both with the planet carrier and with respect to the primary carrier. In one embodiment a set of stationary first masks (20) that allow controlling the radial variation in physical film thickness is arranged between a source (8) of material situated beneath the planets and the substrates. A set of second masks that mask off evaporation angles exceeding a limiting evaporation or incidence angle (β max) for every substrate also corotate with the primary carrier (2), which allows depositing coatings having a prescribed radial film-thickness distribution and a virtually constant density of the coating material over their full radial extents for relatively low, and only slightly varying, evaporation angles.

    摘要: A method for coating substrates (10) for optical components with essentially rotationally symmetric coatings employs a coating system equipped with a planetary-drive system (1) that has a rotating planet carrier (2) and several planets (4), each of which carries a single substrate, that corotate both with the planet carrier and with respect to the primary carrier. In one embodiment a set of stationary first masks (20) that allow controlling the radial variation in physical film thickness is arranged between a source (8) of material situated beneath the planets and the substrates. A set of second masks that mask off evaporation angles exceeding a limiting evaporation or incidence angle (β max) for every substrate also corotate with the primary carrier (2), which allows depositing coatings having a prescribed radial film-thickness distribution and a virtually constant density of the coating material over their full radial extents for relatively low, and only slightly varying, evaporation angles.
