Zusammenfassung: | The utility model relates to a wide angle shimmer camera lens, it is the positive back C of group for the preceding A of group of burden, smooth fence B and focal power to be equipped with the focal power along light in proper order from preceding incident direction backward among the optical system of camera lens, the preceding A of group includes first veneer group and the biconvex lens A -6 who connects airtight from the preceding negative crescent moon lens A -1 who sets gradually backward, burden crescent moon lens A -2, positive crescent moon lens A -3, biconcave lens A -4 and biconvex lens A -5, after organize C and include second veneer group, biconvex lens C -4 and the burden crescent moon lens C -5 who connects airtight from the preceding negative crescent moon lens C -1 who sets gradually backward, by biconvex lens C -2 and biconcave lens C -3. This wide angle shimmer camera lens has the height and separates the image force in 600nm-900nm spectral range, survey the angle of vision be greater than 52, has 1: 1.2 large relative aperture, descends to the camera provides the photosignal in special weather conditions such as rain, snow, mists, produces the high video image of image force that separates. |
