Abstract
The present invention relates to a light large-caliber metal reflector which is composed of a base, a metal layer combined firmly with the base, and a metal reflecting film plated on the metal layer in a vacuum deposition mode, wherein the metal layer can be a metal nickel sheet, or a metal copper sheet or a stainless steel sheet which is 1 to 1.5mm in thickness and can be ground/polished in an optical way. The base which is in a honeycomb structure or a flat plate structure is made of light alloy materials or light metal matrix composite materials, and mainly provides enough strength and rigidity for the metal reflector. The present invention has the advantages that the reflector has simple structure, the defect that nickel plated in a chemical way has insufficient thickness is overcome, and the present invention is suitable for the manufacture of large-caliber metal reflectors.
Description
Technical field
The present invention relates to optical element, specifically be meant the light-weight metal catoptron that a kind of bore is bigger.
Background technology
At present the aperture lightweight metallic mirror mainly contains: with the beryllium metal is expansion coefficient glass such as substrate material surface sintering or the nickel plating heavy caliber metallic mirror (www.hx863.com as optics processing grinding/polishing layer, multispectral scanner beryllium scanning mirror, technology numbering: 123370); With the light aluminum alloy is the heavy caliber metallic mirror of substrate material surface nickel plating as optics processing grinding/polishing layer; With the light aluminum alloy is matrix material, adopts optical reproducing method to make metallic mirror (P.523, optics cold machining process handbook, Lv Maoyu chief editor, China Machine Press, 1991).For the beryllium metallic mirror, owing to will obtain relatively difficulty of large-sized metallic beryllium, therefore making bigbore beryllium metallic mirror is subjected to great restriction.The Al-alloy metal catoptron technology of making by chemical nickel plating on surface is because the thickness of chemical nickel plating generally about the hundreds of micron, thereby can't be used for the making of larger caliber (more than 300-400mm) metallic mirror.The size of optical reproduction metallic mirror is subjected to the influence of optics template surface optics quality and vacuum coating equipment size, has very big limitation in the use.
Summary of the invention
Difficult problem based on above-mentioned existing aperture lightweight metallic mirror existence is made the objective of the invention is to propose a kind of compound lightweight heavy caliber metallic mirror of double-level-metal easy to make.
Lightweight heavy caliber metallic mirror of the present invention comprises: matrix material 1, with the metal level 2 of matrix material 1 strong bonded, metal level 2 on be equipped with metallic reflective coating 3 by vacuum coating.It is characterized in that:
Said metal level 2 be thickness be 1.2mm can optical grinding/polishing the metallic nickel skin.
Said matrix 1 is honeycomb or slab construction, and it is to be made by alloy in lightweight material or light-weight metal based composites, and it mainly provides metallic mirror with enough strength and stiffness.
The invention has the advantages that the simple in structure of catoptron, avoided the shortcoming of chemical nickel plating thickness deficiency, be suitable for the heavy caliber metallic mirror and make.
Description of drawings
Fig. 1 is the structural representation of lightweight heavy caliber metallic mirror.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail: see Fig. 1, matrix 1 adopts the aluminum alloy materials of slab construction, metal level 2 adopts the thick metallic nickel skin of 1.2mm, this nickel skin is a hard nickel, is produced by Shanghai metal tape paper tinsel factory, and concrete manufacture craft is as follows:
At first alloy matrix aluminum 1 and metal level 2 are cleaned in clean-out system, the prescription of clean-out system is:
30 parts of demineralized waters,
The concentrated sulphuric acid 10 parts ± 10%,
Potassium dichromate 1 part ± 10%.
Alloy matrix aluminum 1 after the cleaning and metal level 2 oven dry, and matrix 1 and metal level 2 are composed one with the epoxy glue mixture were placed in 60 ℃ the baking oven curing 24 hours.The prescription of epoxy glue mixture is: bisphenol-A type epoxy resin (100 gram)+imidazole curing agent (8 gram).Then to carrying out optical grinding with metal nickel dam that alloy matrix aluminum 1 firmly is connected, being polished to the plane surface shape of requirement.Place it in the required metallic reflective coating 3 of plating in the vacuum coating equipment at last.The flatness error of metallic mirror is λ/5 after testing.
Above-mentioned matrix 1 and metal level 2 also can adopt the method for welding that they are connected to one, grind/polish the plating reflectance coating then, finally finish the making of catoptron.
