[background technology]
In liquid crystal (LCD) or liquid crystal over silicon (LCoS) optical projection system,, need and to merge to from the three primary colours polarized light of three light paths in the light path for realizing colored the demonstration.More in the industry at present is to adopt the X prism, and this X prism is formed along gluing together along the right angle face by 4 right-angle prisms usually, and the inclined-plane of right-angle prism is as the input face and the output face of light.The output face of the inclined-plane of all the other right-angle prisms after as the three primary colours synthesize white light.The X prism can synthesize the three primary colours polarized light well, but weak point is: form the X prism four right-angle prisms processing and, the design of film system, and the gummed of right-angle prism and film system the rather requirement of strictness is all arranged, increased processing cost virtually.
Just above-mentioned traditional X prism is improved in the industry, as Chinese patent application No. 200710036631.9 a kind of color-combination prism is disclosed, it comprises by two right-angle prisms gummed and forms a foursquare polarization splitting prism (PBS), be coated with polarization beam splitter on the inclined-plane of one of them right-angle prism, paste in regular turn on the right angle face of a right-angle prism and go up quarter-wave plate, bandpass filter, another quarter-wave plate, above-mentioned polarization beam splitter has the light that the polarization by reflection attitude is the S polarization, seeing through polarization state is the function of the light of P polarization, bandpass filter is that the plating spectro-film forms on glass substrate, light with wave band of permeation parts, reflect the function of another band of light, the technology that this patent application is traditional relatively is significantly improved, but still exist structure also complicated, it is lower to close optical efficiency, the shortcoming that manufacturing cost is higher.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of chromatic polarization prism that closes, and is simple in structure, and gummed requires simple, and manufacturing cost is lower, and closes the optical efficiency height.
The utility model is achieved in that a kind of chromatic polarization prism that closes, comprise a polarization splitting prism, this polarization splitting prism is to be square prism by two right-angle prisms along the end face that inclined-plane gummed forms, be coated with polarization beam splitter on the inclined-plane of one of them right-angle prism, it is characterized in that: the wave plate of the fixedly connected dual wavelength of one of them end face of described polarization splitting prism, the outside surface of this wave plate also plates one deck optical filter film.
When described wave plate is the S polarization to incident light, be that the quarter wave plate of ruddiness is again the half-wave plate of green glow simultaneously, and described optical filter film is to the height reflection of ruddiness and the high film system of green glow.
When described wave plate is the P polarization to incident light, be the quarter wave plate or the half-wave plate of ruddiness and blue light, and described optical filter film is the high anti-or high transmittance film system to ruddiness and blue light.
Described polarization splitting prism adopts the mode of gummed or in-depth optical cement to fixedly connected with the wave plate of dual wavelength.
The utility model adopts above-mentioned structure, compares with structure in the past to have following advantage: it is to utilize a kind of wave plate of particular design to combine with polarization splitting prism to realize three kinds of photosynthetic looks of primary colours of red, green, blue.Simple in structure, can produce cheaply to large-sized from small size, and glue together requirement simply, especially manufacturing is low-cost, can be widely used in the Projection Display of LCD or LCoS, particularly the demand of the mobile phone projection demonstration of small size requirement.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structural representation that the utility model closes the chromatic polarization prism.
Fig. 2 is incident light that the utility model the closes principle schematic when being the S polarization.
Fig. 3 is incident light that the utility model the closes principle schematic when being the P polarization.
[embodiment]
See also shown in Figure 1, the chromatic polarization prism that closes of the present utility model, the wave plate 2 that comprises a polarization splitting prism 1 and a dual wavelength, described polarization splitting prism 1 is to be square prism by two right-angle prisms 11 (12) along the end face that inclined-plane gummed forms, be coated with polarization beam splitter 13 on the inclined-plane of one of them right-angle prism, 2 of the wave plates of described dual wavelength are glued on one of them end face of polarization splitting prism 1, and the outside surface of this wave plate 2 also plates one deck optical filter film 3.Described wave plate also can adopt the method for deepening optical cement with combining of polarization splitting prism 1, mainly is to be used for high-power use.
When 2 pairs of incident lights of described wave plate are the S polarization, be that the quarter wave plate of ruddiness is again the half-wave plate of green glow simultaneously, and described optical filter film 3 is to the height reflection of ruddiness and the high film system of green glow.When 2 pairs of incident lights of described wave plate are the P polarization, be the quarter wave plate or the half-wave plate of ruddiness and blue light, and described optical filter film 3 is the film systems to ruddiness and blue light.
The utility model is that to utilize a kind of wave plate of particular design be that the wave plate 2 of dual wavelength combines with polarization splitting prism and realizes three kinds of primary lights of red, green, blue (polarized light) are closed look.Concrete principle is as follows:
One, all be that the S polarization is an example with incident light
Since polarization splitting prism have the polarization by reflection attitude is the S polarization light, to see through polarization state be the function of the light of P polarization.As shown in Figure 2, blue light B directly is polarized Amici prism 1 reflection from the adjacently situated surfaces incident of wave plate 2; And green glow G changes into P light from the position incident of wave plate 2 through behind the wave plate 2, directly is polarized Amici prism 1 transmission to go out; Ruddiness R is from another adjacently situated surfaces incident of wave plate 2, be polarized Amici prism 1 reflection after, also be converted into P light through twice wave plate 2 back and forth, also be polarized Amici prism 1 transmission at last and go out.The polarized light of so just having realized three kinds of colors is by different port incident, at last all from same port outgoing, thereby realizes the effect of closing light.
Two, all be that the P polarization is an example with incident light
When incident light all is the P polarization, need be with one of ruddiness R or blue light B position incident from wave plate 2.As shown in Figure 3, ruddiness R directly is polarized Amici prism 1 reflection from the position incident of wave plate 2; Blue light B is then from the opposite incident of wave plate 2, be polarized Amici prism 1 reflection after, also be converted into P light through twice wave plate 2 back and forth, also be polarized Amici prism 1 transmission at last and go out; Green glow G changes into P light from the adjacently situated surfaces incident of wave plate 2 through behind the wave plate 2, directly is polarized Amici prism 1 transmission and goes out, at last all from same port outgoing.Can be in the effect that realizes closing light at last.When using LCD or LCoS or other modulating equipments to three primary colours light after the actual amount of incident control, exit end will manifest the shades of colour of our needs at last.
In sum, the utility model utilizes a kind of wave plate of particular design to combine with polarization splitting prism to realize three kinds of photosynthetic looks of primary colours of red, green, blue.Simple in structure, and the gummed requirement is simple, makes low cost, can be widely used in the Projection Display of LCD or LCoS.
