Said invention is simple in preparation process.
Description
Technical field
The present invention relates to optical element, specifically be meant a kind of aperture lightweight compound substance catoptron and preparation method who is mainly used in the Space Optical System.
Background technology
In order to solve the surface deformation that the large caliber reflecting mirror deadweight causes, generally adopt light structures to alleviate the weight of catoptron itself.As U.S. Pat 5,076,700 at first disclose a kind of technical scheme that adopts honeycomb sandwich construction in the fused quartz matrix; U.S. Pat 4,035,065 discloses a kind of foamglass sandwich construction that adopts in basal body of reflector; U.S. Pat 176,588 discloses a kind of ceramic honeycomb sandwich construction that adopts in basal body of reflector; Chinese Shanghai Institute of Technical Physics patent " very light large aperture composite reflector ", application number: 01126514.0 and " a kind of low very light large aperture composite reflector that expands that is used for space camera ", application number: 01254216.4 discloses the low alloy that expands of a kind of employing as reflecting surface basic unit, and the centre is the ultra lightweighting catoptron of graphite fiber/epoxy resin panel folder honeycomb sandwich construction.The common ground of above-mentioned these light reflection mirrors is that structure and manufacturing process are generally comparatively complicated, requires very high to process equipment.
Summary of the invention
Based on the problem that above-mentioned prior art exists, it is simple to the objective of the invention is to propose a kind of structure and manufacturing process, and process equipment is required lower aperture lightweight compound substance catoptron and prepares the method for this catoptron.
Light reflection mirror of the present invention comprises: matrix, and with the metallic reflector of matrix strong bonded.Said matrix is to be made by lightweight carbonization sial system (SiCp-Al) material.
The preparation method of light reflection mirror of the present invention can select different manufacture crafts to finish according to the size of catoptron accuracy class and catoptron bore.At 1 more than the wavelength, the catoptron of bore below 300mm can adopt the method for optical reproduction for the surface figure accuracy grade.At 1 below the wavelength, the catoptron of bore more than 100mm can adopt the method for plated film for the surface figure accuracy grade.
Great advantage of the present invention is to adopt the SiCp-Al light material to have the characteristic similar with metallic beryllium as basal body of reflector, and it is simple to have machining, and is low to process equipment and environmental requirement, the manufacture craft characteristic of simple.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, light reflection mirror of the present invention comprises: matrix 1, and with the metallic reflector 2 of matrix strong bonded.Said matrix is to be made by the SiCp-Al material.
The light reflection mirror preparation method comprises two kinds of optical reproducing method and film plating process.
The optical reproducing method concrete steps are as follows:
A. matrix is handled: at first adopt Ginding process that flatness processing is carried out on the surface of SiCp-Al matrix material, flatness is 0.002mm-0.005mm.Then matrix surface is carried out degrease and handle, prescription for the treatment of liquid is as follows:
30 parts of demineralized waters
The concentrated sulphuric acid 10 parts ± 10%
Potassium dichromate 1 part ± 10%.
After matrix immersed treating fluid 30-60 minute, use pure water rinsing, put it in 60 ℃ the baking oven standby subsequently.
B. the preparation of optics template: at first adopt optical grinding/glossing that the substrate K9 glass of optics template is carried out flatness processing; flatness is N=1; Δ N=0.1; then on vacuum coating equipment, plating silicone oil diffusion barrier 201 behind its cleaning surfaces successively; SiO protection mould 203 and metallic aluminium reflective coating 202, the baking oven of putting into 60 ℃ after plated film is finished is standby.
C. above-mentioned SiCp-Al matrix 1 surface of handling well is coated with epoxide-resin glue, then that the one side that is coated with the aluminium mirror coating layer on the optics template is glued together with it, be placed in 60 ℃ the baking oven and solidified 24 hours.After the curing, because the existence of diffusion barrier, optics template and matrix can be separated at an easy rate at the diffusion barrier place, and SiO protection mould and metallic aluminium reflectance coating are bonded on the basal body of reflector securely like this, make thereby finish catoptron.Said Formulaion of epoxy resin is: bisphenol-A type epoxy resin (100 gram)+imidazole curing agent (8 gram).
Optical reproduction quality for the detection optical replica mirror, as reflectivity detection, the detection of rete firmness etc., in reproduction process to adopting same material, the test sample of same processing, processing technology also duplicates, by the measurement of test sample being monitored the optical reproduction quality of catoptron.
The concrete steps of film plating process are as follows:
Matrix is handled identical with above-mentioned A step, adopt conventional chemical nickel plating technology plating nickel dam on matrix then, again the metal nickel dam is ground, polishes, at last in vacuum coating equipment on the metal nickel dam plating reflectance coating, thereby finish the making of the catoptron of high plane precision.
