摘要： A releasable and stress-free securing assembly for an optical element (2, 3) positioned in a centered manner in a mount (1) is provided. The optical element (2, 3) is provided, in the border region which is to be retained, with a beveled surface (6) inclined in the direction of the mount (1). The mount (1) has a groove (4) which is open axially in front of the optical element (2, 3). A ring element (5) which is elastically deformable in the axial direction is pressed in between the beveled surface (6) and groove (4). The angle of inclination of the beveled surface (6) is between 40° and 50°. The boundary (11') of the groove (4) in the region of the optical element (2, 3) is level with a bevel edge (8), which is oriented toward the mount (1), and the boundary (11) of the groove (4) in front of the optical element (2, 3) is undercut at an angle of from 10° to 15°. The depth of the groove (4) is greater than the radius of the ring element (5) by from 0.15 to 0.2 mm, and a free opening between a bevel edge (10), which is located on the optical element (2, 3) toward the center, and the front edge (12) of the undercut boundary (11) of the groove (4) is equal to 0.8 of the diameter of the ring element (5).

摘要： A burnout frame for printing of a transparent original film (4) to a collecting film or printing plate (1) and a simultaneous burning out of non-image-carrying areas by means of a light of short wavelength, comprising a transparent printing glass (6,7,15), which is larger than the largest original film considered to be printed and which has a clear, central part (15) of an optical glass and of a type, which absorbs a part of the light within the ultraviolet wavelength range, particularly a bronze glass and designed to send light through the original film (4), and a diffused part (6-7) of a plastic material, located outside said part, the printing glass on its underside having one or two arrays of vacuum grooves (8,9), designed to hold by suction an original film (4) and possibly also a masking film (5), and the glass part (15) of the printing glass being inserted into the plastic part (6-7) , located on the outside, and being joined to it by means of a glue (16), which forms a light barrier between the glass part (15), and the plastic part (6-7), particularly an optical pure epoxy glue.
