An adjustable support assembly for an object to be accurately positioned relative to a base, in particular for a secondary mirror of an optical mirror telescope, has at least one support structure connected to the base and to the object. The support structure has at least two struts extending in a non-parallel manner relative to each other, where each strut has associated therewith a drivable actuator element in such a way that the actuator element applies a force onto the strut that deflects the strut transversely to the longitudinal extension thereof. The support structure may be supported in an articulated manner relative to the base.

An ultra lightweight mirror blank having a ribbed back side and a smooth front side. The mirror blank is comprised of a core made of fiber insulation strips, arranged to create a strong ribbed surface on the back of the blank. The core is sandwiched in between two or more plates of fused glass.

The invention relates to a long-range optical device comprising at least one sight channel and an image capturing channel with a camera module, wherein the sight channel and the image capturing channel are coupled to one another by means of an adjusting mechanism such that a first image detail observed in the sight channel essentially corresponds to a second image detail captured by the camera module; an interface module for establishing a connection with an electronic terminal; a processing unit; a memory unit, and a support unit, in which support unit the sight channel is arranged, wherein a heat dissipation device is formed between the support unit and the processing unit and/or between the support unit and a housing of the sight channel and/or on the camera module. The invention moreover relates to an observation and image capturing system.

A spectrometer with a Schmidt reflector is described. The spectrometer may include a Schmidt corrector and a dispersive element as separate components. Alternatively, the Schmidt corrector and dispersive element may be combined into a single optical component. The spectrometer may further include a field-flattener lens.

A bipod flexure mount couples an optic to a base while isolating the optic from strain to resist wavefront error. The bipod flexure mount has a distal attachment pad to be coupled to the optic and a proximal attachment pad to be coupled to the base. A pair of beams extend between and couple the distal and proximal attachment pads. The distal attachment pad, the proximal attachment pad and the pair of beams are disposed in and define a planar layer with opposite planar surfaces that are substantially parallel. The bipod flexure mount is relatively flexible about four degrees of freedom and is relatively stiff about two degrees of freedom.

A process for manufacturing an optical element comprising a first step of spinning a circular sheet of a first metallic material for it to adhere to a rotating matrix and form a shell; a second step of assembling the shell on a temporary support; and at least a third step of diamond turning the shell by means of a diamond tool to obtain an optical surface.
