HOLDER FOR FASTENING OF LARGE-SIZE ELEMENT OF OPTICAL-MECHANICAL INSTALLATION (VERSIONS) Russian patent published in 2020 - IPC G02B7/183 

FIELD: optics.

SUBSTANCE: invention relates to laser engineering. Claimed holder includes a holding frame, a set of fasteners and a support frame, which one of the end surfaces adjoins the surface of the optical element and in it, in this zone, a groove is made for arrangement of a sealing gasket, which over the entire length is made with a variable profile, the shape of which is selected depending on the shape of the surface of the optical element in the contact zone with the sealing gasket, and the depth is calculated from the condition of minimizing mechanical stresses in the optical element taking into account its loading. Holder is additionally equipped with a unit for adjusting the position of the optical element along the optical axis, which is located on the side of the support frame and is made in the form of a shell with a flange, the height of which is selected proceeding from the location of the optical element, flange has sealing groove or place for sealing and holes for connection of optical element together with pressure and support frames to element of optical-mechanical installation, and fastening elements connecting the shell with the support frame are elongated bolts, in the heads of which there is a thread for fastening elements of the clamping frame. Support frame is made in the form of a shell with two flanges, the height of which is selected proceeding from the location of the optical element, groove for arrangement of sealing gasket is made in one of flanges, in other flange there is sealing groove or place for sealing and holes for connection of optical element together with pressure and support frames to element of optical-mechanical installation.

EFFECT: reduced susceptibility of the optical element to external effects, as well as simplicity and reliability of the design, ease of installation and repairability.
