UNIT FOR FITTING AND ADJUSTING ASTRONOMIC MIRROR IN TELESCOPE TUBE

摘要

FIELD: optical instrument engineering. ^ SUBSTANCE: unit for fitting and adjusting mirrors with diameter up to 300 mm without worsening shape of surface. Unit for fitting and adjusting astronomic mirror in telescope mirror provides ability of inclination of mirror relatively its center and it has split bushing glued into mirror. Split bushing is connected with movable bushing of convex spherical mirror of hinge. Split bushing moves inside concave spherical hinge of back flange of telescope tube by means of clamp bolts which bolts go through openings of flange into stop ring put onto bead of convex spherical mirror. Deformation of surface of mirror can be excluded due to fact that edge of split bushing , which edge is opposite to lobes, is provided with rest cylindrical bead which is attached with bushing of movable spherical hinge by means of thread ring. Ring spacers are mounted at both sides of bead. Rings rest against bead by three symmetrical protrusions disposed one in opposition to other. Ring spacers are fixed to avoid turn onto bushing of concave spherical hinge by means of stop hinges. ^ EFFECT: ability of adjustment without worsening shape of surface. ^ 7 dwg
