Method of automatically focusing glass-mounted and glassless slides in

The invention relates to a flash device, preferably for transferring a dye matrix which by means of a high-energy light flash is transferred from a radiation-absorbing carrier film by interleaving a mask onto a receiver element. This requires substantially perpendicular irradiation of the transfer plane with a high-energy radiation and a high uniformity of irradiance distribution of the light flash. To achieve this, one or two linearly extending plasma discharge tubes are provided which to concentrate radiation are enclosed by two separate aspheric-cylindrical reflectors, the concentrated radiation being directed through a lamellar louver element arranged downstream of the reflector and impinging on the predetermined transfer plane in a substantially parallel and perpendicular manner.

Flash device for dye transferring

A vehicular headlight, in particular an automobile headlight, including a reflector (1) having a reflecting surface, is capable of illuminating a flat target surface to be illuminated with a desired light distribution by optimal utilization of the light source of the headlight. Therefore the optically effective surface of the headlight is characterized by point asymmetry in substantially all planes cutting said reflecting surface. This can be realized by using a method for producing said optical surface comprising the steps of:
