Description
Technical field of the present invention
The present invention relates to optical preform, or rather, is the optical preform with an adjacent partially hardened resin bed, and they are to be used to prepare optical articles.
Technical background of the present invention
Normally by polymerisable resin directly being carried out die casting or by half-finished blank being ground to form product on request, wherein this half-finished blank is made by polymerisable resin in advance, prepares optical element, lens of ophthalmic etc. for example.Also can use the plasma polymerization effect, centrifugal rotational casting method, casting or photograph resemble technologies such as flat band method according to the order of sequence, and preparation is as the optical element of multiple layer combination.Under any circumstance, the optical element of preparation all will satisfy certain optical technology requirement.
In many application, during for example ophthalmic lens is used because the kind quantity of the optical characteristics of required change is too many so that to the optical element that might need all to carry out prefabricated can be infeasible economically.Therefore, in the preparation process of multifocal ophthalmic lens, normally take two steps: 1) molded semi-finished product blank, 2) grind above-mentioned uncompleted surface, to form final predetermined product.
The process of preparation ophthalmic lens is very time-consuming very expensive again.Constantly the gushed out technology of many preparation lens of its result.For example, Blum (U.S. Pat 5,219,497) has proposed to resemble the method for casting a polymerizing resin thin layer on the outer surface of (vision) lens or semi-finished product blank at a free hand drawing, and wherein these semi-finished product provide additional multiplication factor on lens.Usually, in the single image lens, comprise, contain the distance regulation that any needed double-curved surface is proofreaied and correct, and the range correction in the lens area that is provided by the lens semi-finished product has been provided the resin bed that resembles die casting on (vision) lens at free hand drawing.Greshes (United States Patent (USP), US 4,190, and 621) a kind of die casting method has been described, it is included in clamping lenticular blank on the anchor clamps, and the mould of coupling curvature (degree) is placed on below lens, wherein gets involved the liquid resin layer between mould and lens prefabrication.Verhoeven (U.S. Pat 4,623,496) has disclosed a kind of method, promptly a thin resin layer is moulded on the optical preform with spherical geometry profile.Ito (U.S. Pat 4,536,267) but a resin that the light that combines with light trigger and thermoplastic initator closes has suddenly been described.Toh (US 4,912,185) has described a resin that is used to prepare the photopolymerization of various lens.
Under various situations, can cause some inconvenience with liquid resin die casting lens.For example, the transportation of reactive fluid and transmission.In addition, the contraction that forms in hard solidification process can make lens generation optical skew (distortion).
General introduction of the present invention
The present invention can solve the above-mentioned inconvenience that exists in the prior art, and an optical preform of being made up of an optical article wherein is provided, and for example free hand drawing resembles (vision) lens.The latter has an adjacent subsclerotic resin bed.This adjacent layer can be fit to mould, and further hard solidify (for example crosslinked), so that improve the optical characteristics of prefabrication on demand.Can be placed on above-mentioned adjacent layer on the surface of (with in advance, or later) optical article.
In addition, can before optical article being placed and abutted against on the mould, in advance above-mentioned subsclerotic resin bed be placed on the optical article.Perhaps, before optical article being placed and abutted against mould, in advance above-mentioned subsclerotic resin bed is placed on the die surface.Under any circumstance, the above-mentioned die surface that can be used to place this subsclerotic resin bed manifests convex or spill usually.
Can prepare above-mentioned prefabrication in large quantity, and be stored in and distribute granting place, it is easy to change makes many optical goods, for example polishing is spherical or aspheric, toric, free hand drawing resembles (vision), and is bifocal, multifocal or the semi-finished product blank that goes forward one by one, ophthalmic lens or lens prefabrication.Other optical goods can also comprise mould, intraocular lens, and contact lens or other optical elements, as be used for that optical signal is handled or the optical element of optical computing.
Though a mould can be used for determining the final topographical structure of above-mentioned subsclerotic resin bed.Yet this shape and structure also can be accomplished by not needing with the multiple known treatment method of mould.For example rotate (centrifugal) method, spraying process, infusion process and photograph flat band method.As an example, can form subsclerotic polymeric layer with rotary process.Can make that in rotary course this polymeric layer is softening also to flow, to form required shape and structure with arbitrary this subsclerotic polymeric layer of heating means heating.When this subsclerotic polymeric layer reaches desirable flowability and holding property of viscosity, just can come into effect the illumination curing process.When this subsclerotic polymeric layer continues rotation, just proceed the illumination curing process.Above-mentioned illumination curing makes this polymeric layer further harden into final shape.According to used initator and Chemical composition that, this method can have oxygen atmosphere or oxygen-free compression ring border, for example enforcement in the presence of the nitrogen is being arranged.Can be with visible light or ultraviolet, or dual-purpose both, carry out illumination curing.
