摘要： PROBLEM TO BE SOLVED: To improve a holder which itself is known in such a manner that the holder is made usable even in an optical system particularly having high performance by optimizing an intrinsic influence quantity with respect to the surer holding of optical components. SOLUTION: The angle of inclination of a chamfered surface 6 is set in a range of 40 to 500 and a boundary wall 11 of an insert groove 4 existing within the range of the optical components 2 and 3 is placed at a height of a chamfered edge facing a socket 1. The boundary wall 11 of the insert groove 4 existing in front of the optical components 2 and 3 is undercut at an angle of 10 to 15 deg., by which the depth of the insert groove 4 is made larger by 0.15 to 0.2 mm than the radius of an annular element 5. The free opening between the chamfered edge 10 existing on the optical components 2 and 3 and the front edge 12 of the undercut boundary wall 11 of the insert groove 4 is made equal to 0.8 times the diameter of the annular element 5.

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： At the mounting (1) to hold an optical lens (3) in a center position without tension, the edge of the lens (3) has a chamfered surface (6) angled towards the mounting (1). The mounting (1) has an open groove cut (4), axially in front of the lens (3), and an elastic ring unit (5) with axial distortion is pressed in place between the chamfered surface (6) and the groove cut (4). The angle of the chamfered surface (6) is 40-50 deg , so that the lens lies at the mounting edge (8) when against the limit (11) of the groove (4). The groove limit (11), in front of the lens (3), is cut back at an angle of 10-15 deg . The groove cut (4) has a depth of 0.15-0.2 mm larger than the radius of the ring unit (5). The free opening between the mounting edge (10) on the lens (3) and the leading edge (12) of the cut-back limit (11) is 0.8 times the dia. of the ring unit (5). The ring unit (5) material has a Shore hardness of 70.
