The utility model relates to a polymer reflector for a large-aperture folding telescope, which belongs to the polymer reflector for a large-aperture folding telescope involved in the technical field of astronomical optical instruments. The technical problem to be solved by the present invention is to provide a polymer reflector for a large aperture folding telescope. The technical solution for solving the technical problem is: the invention includes a polymer mirror substrate, a metal film layer, a nickel-phosphorus alloy film layer, and an optical reflection film layer. On the optically polished polymer mirror substrate, electron beams are used to deposit metal film layers, electroless nickel-phosphorus alloy film layers are deposited on the metal film layers, and optical reflective film layers are deposited on the nickel-phosphorus alloy film layers by electron beams. The polymer reflector is light in weight, strong in shock and vibration resistance, not easily damaged, improves application efficiency and prolongs service life.
Description
One, technical field: the invention belongs to the polymkeric substance catoptron that the collapsible telescope of a kind of heavy caliber that relates in the astronomical optics Instrument technology field adopts.
Two, technical background: scientific practice makes people recognize the operating distance of astronomical optics scope and the energy information that can collect, is that the size with bore has direct relation, and bore is big more, and the distance of observation is far away more, and collected energy information is just many more.Yet the size of the material of the optical mirror of heavy caliber astronomical telescope is also big more, such as, the material of the optical mirror of the above bore of 200cm is very rare, and suitable difficulty is manufactured also in the processing of minute surface face shape.Therefore, can make the country of the optics industry prosperity of the above astronomical telescope of bore 200cm in the world, optical mirror is all adopted folding splicing construction, with several small-sized eyeglasses, splice bigbore optical mirror, promptly solved to obtaining the difficult problem of large scale optical mirror base material, solved the difficulty of face formation type again.
After the 1970s and 1980s in twentyth century, it is in the above astronomical telescope of 200cm that the U.S., USSR (Union of Soviet Socialist Republics) and Germany make bore, to manufacturing of optical mirror, all adopted accordion structure, the prior art the most approaching with the present invention, be " vacuum coating " that publishing house of Liaoning University publishes, Dec calendar year 2001 first published P
68, Shenyang, November calendar year 2001.The collapsible eyeglass that adopts as shown in Figure 1, is to do substrate 1 by optical glass, and evaporation multilayer optical reflectance coating 2 constitutes in substrate 1.As evaporating Al on substrate of glass
2O
3Silver-plated again (Ag).Because the ratio of material is great, the splicing of polylith small mirror makes that the weight of whole optical mirror is big, is difficult to support, and simultaneously, makes the formed optical mirror of substrate with optical glass material.Impact strength is low, when instrument at transportation environment or when being subjected to bigger vibration, optical mirror is damaged easily, and influences the result of use of astronomical telescope.
Three, summary of the invention: for preponderance and the lower shortcoming of impact strength that overcomes key component-optical mirror in the above-mentioned astronomical telescope, the object of the invention is to alleviate the weight of optical mirror, improve shock resistance, strengthen serviceable life and effect, the new polymers catoptron that the collapsible telescope of a kind of heavy caliber of ad hoc meter adopts.The technical problem to be solved in the present invention is: provide a kind of heavy caliber collapsible telescopical polymkeric substance catoptron.The technical scheme of technical solution problem comprises polymkeric substance mirror substrate 3, metallic diaphragm 4, nickel-phosphorus alloy rete 5, optical reflection rete 6 as shown in Figure 2; Through on the polymkeric substance mirror substrate 3 of optical polish,, on metallic diaphragm 4,, on nickel-phosphorus alloy rete 5, use electron beam deposition optical reflection rete 6 with electroless plating nickel-phosphorus alloy rete 5 with electron beam depositing metal membrane layer 4.
Principle explanation: adopt of the substrate of the less high molecular polymer of proportion as catoptron, alleviated the weight of catoptron undoubtedly greatly, and polymkeric substance easy-formation shock resistance is strong, through on the polymkeric substance mirror substrate of plastic polishing, the highly reflecting films layer shock resistance that adopts electron beam deposition and electroless plating way to form is strong, therefore, it is very suitable adopting the optical mirror that this kind polymkeric substance catoptron splices astronomical telescope.
Good effect of the present invention: the polymkeric substance catoptron is in light weight, the anti shock and vibration performance is strong, is difficult for being damaged, and improves serviceable life and application efficiency.
Four, description of drawings: Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present invention, and Figure of abstract also adopts Fig. 2.
Five, embodiment: the present invention implements by structure shown in Figure 2, polymkeric substance mirror substrate 3 adopts polyaryletherketone, metallic diaphragm 4 adopts manganese or copper (Mo or Cu) metal, and nickel-phosphorus alloy rete 5 adopts nickel-phosphorus alloy (Ni, P), and optical reflection rete 6 adopts aluminium (Al) reflective coating.
