Description
Technical field
The invention belongs to the manufacture method of optical element manufacturing, particularly a kind of color-combination prism.
Background technology
Color-combination prism is a square four prisms cylinder that is formed by four isosceles right angle trigonometry prism gummeds, as shown in Figure 1.Color-combination prism to green glow G for seeing through, and ruddiness R and blue light B are reflecting on two diagonal line faces respectively, the effect of color-combination prism is that red, blue and green three coloured light are exported white light from the synthetic back of three direction incidents of this color-combination prism from the four directions, throw in screen. the coplanarity of two diagonal line faces of this color-combination prism, promptly 180 ° accuracy requirement is very high.
Japan day east (NITON) company, starting color-combination prism first produces in batches, its processing technology: make four high precision isosceles right angle trigonometry prisms earlier, these four high precision isosceles right angle trigonometry prisms are distinguished plated film by technical requirement: first plates anti-red film at a right angle face, second is plated anti-red film at a right angle face, another right angle face plates anti-blue film, and the 3rd is only plated anti-blue film at a right angle face, the 4th plated film not; Then these four right angle isoceles triangle prisms are composed a color-combination prism, it is synthetic to finish red bluish-green (RBG) three coloured light, throws in screen then.The right angle precision of this technological requirement right angle isoceles triangle prism reaches the rad level, and the right angle crest line is sharply complete, after before the right angle face plating reflectance coating, must anti-another right angle face have a surplus film and sputter, when four right angle isoceles triangle prisms glue together, with two the reflecting surface coplanes of the inhomogeneous technology of glue-line in the hope of two reflecting surface coplanes of ruddiness R and blue light B.This technology not only processing capacity is big, complex process, and because the error at the right angle of four right angle isoceles triangle prisms, intermediate gaps is inserted with inhomogeneous glue-line, and the combined reflecting surface that therefore will form high-precision 180 ° of blue lights and ruddiness is inconvenient.
Thereafter, Nikon (NIKON) company is that representative improves above-mentioned technology, its technology still will be processed four high precision right angle isoceles triangle prisms, plate anti-red film in accordance with regulations earlier, compose two pairs then, " big face " polishing again of every pair of prism, wherein " the big face " of a pair of prism plates anti-basket film again, and two pairs of prism glue become a color-combination prism then.The advantage of this job operation is the sputter that need not prevent or disappear, and two reflectings surface of a shade such as blue light are affirmed strict coplane simultaneously, must proofread and correct the problem of the coplane of another coloured light ruddiness two reflectings surface during gummed.But this technology still has further improved necessity.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of manufacture method of color-combination prism is provided, and this method requires technology simple, and cost is lower, and can obtain very high-precision color-combination prism.
Technical solution of the present invention is as follows:
A kind of manufacture method of color-combination prism is characterized in that comprising the following steps:
1, a kind of manufacture method of color-combination prism is characterized in that comprising the following steps:
1. get the right angle isoceles triangle prism that the refractive index identical materials is made two effectiveness of classifications, the length of each right angle isoceles triangle prism is the twice of color-combination prism length, and the right angle crest line allows the 0.1-0.2mm defective;
2. on a right angle face of the first right angle isoceles triangle prism, plate anti-red film;
3. the right angle face with the plated film of the first right angle isoceles triangle prism glues together mutually with the right angle face of the uncoated second right angle isoceles triangle prism, forms cemented prism;
4. the big face to described cemented prism carries out optics processing, and big of the optics of formation effectiveness of classification is cut into this cemented prism two isometric sub-cemented prisms then;
5. big of optics to one of them sub-cemented prism plates anti-blue film;
6. big of the optics that at last big of optics has been plated the sub-cemented prism of film glues together with the big face of optics of another sub-cemented prism of plated film not, makes color-combination prism.
As another kind of manufacture, color-combination prism also has following manufacture method, it is characterized in that comprising the following steps:
1. get the right angle isoceles triangle prism that the refractive index identical materials is made two effectiveness of classifications, the length of each right angle isoceles triangle prism is the twice of described color-combination prism length;
2. on a right angle face of the first right angle isoceles triangle prism, plate anti-blue film;
3. the right angle face with the plated film of the first right angle isoceles triangle prism glues together mutually with the right angle face of the uncoated second right angle isoceles triangle prism, forms cemented prism;
4. the big face to described cemented prism carries out optics processing, and big of the optics of formation effectiveness of classification is cut into this cemented prism two isometric sub-cemented prisms then;
5. big of optics to one of them sub-cemented prism plates anti-red film;
6. at last big of optics is plated big of the optics and big gummed of optics of another sub-cemented prism of plated film not of the sub-cemented prism of film, made color-combination prism.
Technique effect of the present invention:
1, at first makes the right angle isoceles triangle prism of two effectiveness of classifications, the right angle precision that single right angle isoceles triangle prism is made needn't require a second class precision, only get final product for effectiveness of classification, the right angle crest line of single right angle isoceles triangle prism needn't be made excessive demands no chipping, sharp keen, allows the 0.1-0.2mm defective.
2, to the anti-blue film of plating on the first right angle face of the first right angle isoceles triangle prism, or during anti-red film, needn't protect, also need not go the processing of sputter behind the plated film the second right angle face;
3, on principle, because therefore the adjacent two jiaos of equal supplementary angles each other of cemented surface can obtain the coplanarity that any two reflectings surface have very high degree of precision.
4, in a word, the present invention only adopts general precision processing right angle isoceles triangle prism, can process to have very high-precision color-combination prism.
