Abstract
The present invention relates to technology for manufacturing a unidirectional diaphanous spectacle lens which can form a holographic image with light stability and a manufactured product thereof. The technology for manufacturing a spectacle lens with a laser holographic image is characterized in that photosensitive gelatin layer which is prepared by ammonium dichromate is coated on a transparent spectacle lens, and then, the transparent spectacle lens is placed on a laser light path; a reflecting motherboard used for recording the information of the holographic image is arranged behind the light path of the spectacle lens; one uniform laser reaches the reflecting motherboard after the laser penetrates through the transparent spectacle lens on which the photosensitive gelatin layer is coated firstly, and then, reflection light of the motherboard irritates on the spectacle lens; after exposure for one to thirty seconds, the spectacle lens is put into a film hardening agent for hardening a film, is put into water, and is immersed and washed. Then, the spectacle lens is put in an organic solvent and is dehydrated; thus, images can be displayed. After the spectacle lens is dried, a transparent optical epoxy resin layer is coated on the surface on which the photosensitive gelatin layer is coated, and another spectacle lens is covered on the transparent optical epoxy resin layer to achieve the sealing degree.
Description
The present invention is about a kind of manufacturing process and goods thereof that can form the stable hologram image of light and have the lens of unidirectional printing opacity.
Existing lens or transparent or coloured form are comparatively dull, this mainly due to this certain products of glasses to due to the high request of transmittance, laser hologram image goods related to the present invention once had introduction on more books such as " laser holographys " in addition, also once disclose title at home on patent CN1098205A and the CN1023034C document and be respectively " laser hologram image handicraft " and relevant laser hologram image technology such as " the molded making method of holo-rainbow and the goods thereof of band embossment ", so far, if adopt goods that laser holography obtains on carriers such as clear glass, all have all light tight phenomenon in two sides, this laser hologram image goods can not be applicable to manufacturing of lens fully.
The object of the invention is exactly the laser hologram image technology will be combined with the lens manufacturing technology in the hope of obtaining the abundant lens that is particularly suitable for making sunglasses again of pattern.
Described lens manufacturing process with laser hologram image is characterized in adopting the sensitive gelatin layer of ammonium dichromate preparation to be coated on the transparent lens, then this lens places on the laser optical path, after the light path of lens, be provided with the reflection motherboard of recording holographic image information, a branch of uniform laser at first transmission arrives the reflection motherboard after crossing the transparent glasses sheet that is coated with the sensitive gelatin layer, the reflected light of motherboard shines lens again, after exposure in 1～30 second, lens is placed on post bake in the hardening bath, putting into bubbly water again washes, then be placed on dehydration of organic solvent and get final product video picture, after the drying, coat the transparent optical epoxy resin layer at this face of sensitive gelatin layer, reach seal degree above covering with another sheet lens.
Another set of technological process of the present invention is except laser optical path is arranged difference, all the other are all identical, this cover laser optical path arranges scheme as follows: laser is divided into two bundle laser behind the beam splitting lens, wherein a branch of uniform laser directly is transmitted to the transparent glasses sheet front that is coated with the sensitive gelatin layer, and another restraints the reverse side of uniform laser radiation to the reflection motherboard back reflection that records hologram image information to above-mentioned transparent glasses sheet.
Ammonium dichromate gelatin layer recited above is made up of 3～4% gelatin and 0.5～1.5% ammonium dichromate aqueous solution.And hardening bath is made up of distilled water, sodium thiosulfate, anhydrous sodium sulfite, glacial acetic acid, boric acid, aluminium potassium sulfate.
Via the prepared two layers of compound spectacles sheet of above-mentioned process energy reproduction laser light hologram image under white light; wherein; in one side is observed; clear picture still is the transparent light that do not hinder and observe from another side, does not also influence sight line; greatly enriched the color and luster image of lens; in addition, have the ultraviolet function that absorbs in the sun after the video picture of sensitive gelatin layer, can play the effect of protection eyes.
Further illustrate the present invention below in conjunction with embodiment.
Figure of description 1 is an embodiment of the invention light path synoptic diagram.
Accompanying drawing 2 is the another set of light path synoptic diagram of the embodiment of the invention.
Wherein, 1: laser instrument, 2: electric timing switch, 3: beam expanding lens, 4: wave filter, 5: lens, 6: reflection motherboard, 7: beam splitting lens, 8: catoptron, 9: collimating mirror.
At first prepare sensitive gelatin, get and analyze pure gelatin 20 grams, adding distil water to 500 milliliter, heating stirs, and the temperature of heating generally is no more than 40 ℃; Ammonium dichromate 5 gram adding distil waters stir for 500 milliliters in addition; Above-mentioned 50 milliliters ammonium dichromate solution poured in 500 milliliters the gelatin solution, stir and refilter, promptly get sensitive gelatin, sensitive gelatin is coated in through cleaning on the lens of handling with oven dry, and this lens 5 placed Fig. 1 or light path position shown in Figure 2, present embodiment adopts tungsten disc inferior ion laser device, as shown in Figure 1, the laser that laser instrument 1 produces is through electric timing switch 2, beam expanding lens 3, wave filter 4 effects such as camera lens such as grade, make laser become a branch of uniform laser, this a branch of uniform laser is transmitted to reflection motherboard 6 through lens 5, these motherboard 6 laser light reflected have write down motherboard hologram image information and have reflexed on the lens 5 again, make the lens 5 of coating sensitive gelatin note the information of motherboard 6 hologram images.As shown in Figure 2, the laser that laser instrument 1 produces also is divided into two bundle laser through electric timing switch 2 and wave filter 4 backs behind beam splitting lens 7, after catoptron 8 and beam expanding lens 3 and collimating mirror 9 adjustment, a branch of uniform laser directly is transmitted to the front of the transparent glasses sheet 5 that is coated with the sensitive gelatin layer, and another restraints the reverse side of uniform laser radiation to reflection motherboard 6 back reflections that record hologram image information to above-mentioned transparent glasses sheet.Present embodiment is 1～30 second with laser radiation (exposure) time, how long should consider laser intensity and operating power height on earth, lens 5 after the exposure is put into lens 5 after will exposing again behind the hardening bath post bake of being made up of following component and is put into bubbly water and wash, and described hardening bath is formed with the preparation situation and is described as follows:
Hardening bath proportioning: 4000 milliliters of distilled water
Sodium thiosulfate 1200 grams
Anhydrous sodium sulfite 75 grams
Glacial acetic acid 67.5 grams
Boric acid 37.5 grams
Aluminium potassium sulfate 150 grams
Add medicine one by one by said sequence, solution temperature generally can not be above 60 ℃ about 45 ℃.
The lens that is coated with sensitive gelatin 5 after bubble is washed is put into the isopropyl alcohol dehydration and can be developed, taking out the lens 5 developed dries being lower than under 80 ℃ of situations, certainly oven dry is preferably between 40～50 ℃, is comparatively ideal processing with the oven dry of about one hour time.Coat uniform one deck with optics with transparent epoxy resin with drying lens with hologram image, with another sheet lens it is carried out the capping encapsulation process after processing such as edging get product, pin for the purpose of the present invention, by the goods of the present invention that two layers of lens are composited, preferably should select to have at least a slice is good for the colored transparent lens.
