Description
Technical field
The utility model relates to camera head field, is specifically related to a kind of lens devices for low light environment light enhancing under water.
Background technology
Along with people are to the growth of the exploration desire of the Nature, people are more and more interested in underwater camera.But due to aqueous phase be a kind of optically denser medium for air, according to optical principle, when light is propagated between two media, at optically thinner medium, light is larger with the angle of normal than optically denser medium light with the angle of normal, incident angle and refraction angle are positive correlation, and sun altitude is lower, and namely incident angle is larger, the refraction angle be then irradiated in water is larger, the light path reaching the light of same depth is longer, and the weakening be subject to is more, and the illumination therefore in water is less.Meanwhile, when sun altitude is lower, the light of refraction is fewer, and the light of reflection is more, and the light irradiated in water inlet is fewer, and impurity, planktonic organism, aquatic animals and plants etc. in the water surface and water all can keep the sun off, and affect the illumination of sunlight in water.Therefore, because light can deep fades in water, the illumination in water is less, often because insufficient light causes imaging unintelligible in underwater photography or shooting process.
Light for common shooting equipment strengthens existing more research, as China applies for a patent CN101655598A, disclose a kind of lens devices and this lens devices is applied in camera wherein, this lens devices possesses good spotlight effect, but not possessing the functions such as withstand voltage due to it, the optically focused being difficult to adapt to underwater camera process requires the shooting standard in especially deep-sea.
Utility model content
For above technological deficiency, the utility model object is to provide a kind of lens devices that can strengthen camera or video camera light under low light environment, solve underwater camera or video camera unsharp problem of imaging under low light environment, be particularly useful for deep-sea camera head.
The utility model is achieved through the following technical solutions:
For a lens devices for low light environment light enhancing under water, comprise the preposition plano-convex lens be arranged in order from thing side to image side, high pressure resistant window mirror, rearmounted plano-concave lens and rearmounted plano-convex lens.Described high pressure resistant window mirror side and preposition plano-convex lens are fitted, and opposite side and rearmounted plano-concave lens are fitted, after described rearmounted plano-convex lens is positioned at described rearmounted plano-concave lens.
The photocentre of described rearmounted plano-convex lens is 0.1 ~ 2cm (please provide correct data area) apart from the distance of the photocentre of rearmounted plano-concave lens.
Described preposition plano-convex lens, high pressure resistant window mirror, the central shaft of rearmounted plano-concave lens and rearmounted plano-convex lens on the same line.
Described preposition plano-convex lens and described rearmounted plano-convex lens all to thing lateral projections, described rearmounted plano-concave lens recessed to face, image side.
Described high pressure resistant window mirror is rectangle.The binding face of described preposition plano-convex lens and rearmounted plano-concave lens and high pressure resistant window mirror is plane.
Light-ray condensing as much as possible is become focused beam by described preposition plano-convex lens in high pressure resistant window mirror, by becoming divergent beams after rearmounted plano-concave lens, be corrected to parallel beam by rearmounted plano-concave lens again, thus increase the luminous flux arriving camera or camera.
Compared with prior art, the utility model has the following advantages:
The utility model structure is simple, rationally distributed; Forward, spotlight effect is stronger, and aberration is little, good imaging quality for the convex surface of plano-convex lens; Be provided with high pressure resistant window mirror, the lens devices of camera or video camera light under low light environment can be strengthened, solve underwater camera or video camera unsharp problem of imaging under low light environment, especially can adapt to the photography and vedio recording process in deep water.
