High definition is video camera lens under water

The utility model relates to a high definition is video camera lens under water, include first lens, second lens, guang lan, third lens, fourth lens, the 5th lens and the 6th lens of following the light incidence orientation and setting gradually, first lens is the convex -concave negative lens, the second lens is the convex -concave positive lens, third lens is convex -concave negative lens, thefourth lens is unsmooth positive lens, the 5th lens is the convex -concave positive lens, the 6th lens is dull and stereotyped protection glass. This camera lens adopts the method that the centre of sphere of the income pupil position that makes whole optical system and the first face of first lens coincides mutually, guarantees the light beam unbiased and rolls over ground and get into the waterspace, can not only adapt to the different depth of waters, reach the effect of high definition, simple, the sexual valence relative altitude of optical structure in addition at different depth of water homoenergetics. 本实用新型涉及
