Abstract
The invention discloses a colored optical plastic light gathering lens and manufacturing technology, which is characterized by the following: stirring 100 part polycarbonate resin, 5 part naphtocyclinon and 1 part anthraquinone through mechanic stirrer evenly; casting precisely; polishing mould core; adopting PVT theory as induction and dynamic parameter control as facility; making the supplementary layer as auxiliary plastic non-spherical moulding technology.
Description
Technical field
The present invention relates to a kind of optical lens, especially relate to a kind of color optical plastic condensor and production technology.
Background technology
The general used starting material of optical plastic lens are organic glass (PMMA) or polystyrene (PC), and the lens that this class material is made are the water white transparency body, and its spectral characteristic as shown in Figure 1; When this lens are applied in the systems such as scanner as condenser (Fig. 2 [1]), often needing to increase color filter is red glass (Fig. 2 [2]), its structure as shown in Figure 2, light can only be passed through in specific SPECTRAL REGION, make it to have spectral characteristic as shown in Figure 3, optically focused is to detector (Fig. 2 [3]) again.System architecture is comparatively loaded down with trivial details so in use, cooperation between the parts tends to make system reliability to reduce, what is more important is owing to the sexavalent chrome that color filter (red glass) contains exceeds standard, and many countries forbidding in quilt Europe, America has restricted the market development of this series products greatly.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the invention provides a kind of color optical plastic condensor.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of color optical plastic condensor, described condenser is that special toner is mixing in raw material, form by precise injection molding, make it have specific spectral characteristic, light ends or conducting in specific scope.Its technological process of production is: the selection of a. colour system, according to the spectral characteristic requirement of needed coloured optical plastic, select single colour system, and by the spectrum test of theoretical analysis and single look, the curve of spectrum after the stack is adhered to specification substantially; B. mixed raw material, selecting transparent polycarbonate for use is matrix, the dyestuff of selecting among the blend step a, and described dyestuff comprises Naphtocyclinon and anthraquinone, above-mentioned raw-material proportioning (weight ratio) is: 100 parts of polycarbonate: 5 parts of Naphtocyclinons: 1 part of anthraquinone fully mixes with machine mixer; C. precise injection molding, the mixture temperature of injection molding material is controlled at 200 ℃-220 ℃, and injection time roughly is controlled at 30-60 second/mould according to the big or small thickness difference of parts, and injection pressure is 80-100MPa; D. optical property survey to be transferred, be injection molded into product after, need its focal length of test on 550 focometers, its face type of test on from-Talysurf aspheric surface face type detector; E. product inspection.
Described dyestuff Naphtocyclinon and anthraquinone are Powdered, and its particle size range is the 70-100 order; After described injection temperature is selected, be controlled at ± 0.5 ℃ float.
Adopt technique scheme, the beneficial effect that brings to the present invention is: the present invention gathers light, colour filter in one, use and make system architecture simplify a lot, save parts, reliability also improves greatly, and in light weight, good optical properties, the whole in addition optical property requirement that has reached system, the composition in the lens meets European environmental protection standard, is convenient to the developing of international market.

Accompanying drawing 5 is a kind of user mode structural representations of the embodiment of the invention.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: color optical plastic condensor of the present invention, be according to the design needs, light is ended or conducting in specific scope, special toner is mixing in raw material, form by precise injection molding, make condenser have specific spectral characteristic, selected colour system material is an environment-friendly type, nontoxic, can reach European Union's standard.
The present invention is with 100 parts of polycarbonate, 5 parts of Naphtocyclinons, 1 part of anthraquinone, fully mix with machine mixer, wherein Naphtocyclinon and anthraquinone are Powdered, particle size range is the 70-100 order, by precise injection molding, core rod glossing, with the PVT theory is guidance, and dynamic parameter is controlled to be means, and layer of compensation is auxiliary plastic aspherical element moulding process.
Referring to Fig. 4 and Fig. 5, be used for the barcode scanner optical system, adopt coloured optical concentration mirror of the present invention, substituted original general optical plastic lens and the combined structure of optical filter.Coloured optical concentration mirror 1 of the present invention combines in the light from scanning mirror (scan mirror) on the optically focused detector 3, because the laser of this system applies 650nm, so coloured optical concentration mirror of the present invention should make it to have spectral characteristic as shown in Figure 3 with the light ray cut below the 650nm.System architecture is simplified like this, saves parts, and reliability also improves greatly, and good optical properties makes the receiver optical noise reach minimum, the environmental protection of the composition in this outer lens, meet European environmental protection standard.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
