Embodiment Construction

[0022] Such as figure 1 As shown, it is a schematic diagram of the support structure of the reflector supported by the method of the present invention. The main steps of the micro-stress assembly flexible support method of the reflector of the present invention are as follows:

[0023] (1) if figure 2 As shown, lightweight processing is carried out on the back of the reflector 1, and the lightweight form can be composed of regular figures such as triangles, quadrilaterals, hexagons and circles (triangles, quadrilaterals and circles are used as lightweight forms in the accompanying drawings), The central column 101 is a mounting hole, and the inner surface needs to be ground to ensure its cylindricity and thus ensure bonding accuracy and bonding reliability;

[0024] (2) if image 3 and Figure 4 As shown, the flexible mandrel 2 is an equilateral triangular structure, a hollow cylinder 201 is processed in the middle, and a connecting part 202-204 of cuboid structure is proc...

Abstract

The invention discloses a micro-stress assembly flexible supporting method of a small-calibre micro-crystal glass material reflector. The method comprises the following steps of: firstly, carrying out lightweight processing on the back of the reflector, and processing a central column in the centre of the back; secondly, processing a flexible core shaft having an equilateral triangular structure, processing a hollow cylinder in the middle of the flexible core shaft, respectively processing a connecting part having a cuboid structure at three angles, processing three rectangular through holes between the cylinder and the connecting part, and processing a flexible discharging groove, a mounting hole and a pin hole in the connecting part; and finally, directly bonding and fixing an outer surface of the cylinder of the flexible core shaft with an inner surface of the central column at the back of the reflector. By the method, the positioning accuracy of the reflector is improved integrally, temperature adaptability is improved, a forced environment of the reflector during assembly is improved, and optical aberration such as field curvature and astigmatism generated by compression in the conventional mode is eliminated.

Description

technical field [0001] The invention relates to a mirror supporting method. Background technique [0002] In optical instruments, the use of glass-ceramics as reflective materials is the most mature and commonly used means of optical reflection imaging. The use of glass-ceramic as the reflector can reduce material cost and processing cost, and its surface is directly coated without modification, which increases process reliability. [0003] Since the glass-ceramics is a traditional reflector material, its elastic modulus is low, and the reflector is easily deformed by the assembly stress during assembly; at the same time, due to the small thermal conductivity and specific heat of the glass-ceramics, the reflector is in operation. Mirrors are susceptible to thermal deformation caused by environmental temperature changes, which affects imaging quality. These characteristics determine that the mirror assembly should always be in a state of micro-stress or no stress during the...
