An 8k ultra-clear zoom visible light TV camera lens

Abstract

The present invention relates to the field of optical instruments, and in particular to an 8K ultra-clear zoom visible light TV camera lens, wherein the front fixed group is composed of a positive first double-convex lens, a first negative meniscus lens and a first glued group in which the first positive meniscus lens is in close contact. , the second positive meniscus lens, and the third positive meniscus lens; the variable power group is composed of the second negative meniscus lens, the second cemented group of the first biconcave lens and the second biconvex lens, and the third negative meniscus lens The compensation group is composed of the fourth positive meniscus lens, the fourth negative meniscus lens and the third double-convex lens in close contact with the third cemented group, and the fourth double-convex lens; the rear fixed group is composed of the fifth positive meniscus lens The fourth cemented group in which the lens is in close contact with the second biconcave lens, the sixth positive meniscus lens, the fifth cemented group in which the fifth negative meniscus lens is in close contact with the fifth biconvex lens, the sixth negative meniscus lens, and the seventh negative meniscus lens lens, the eighth negative meniscus lens and the sixth double-convex lens in close contact with the sixth cemented group. The lens has the characteristics of large target area, large aperture, and small distortion, and can match 8K (40 million pixels) ultra-high-definition cameras.

Description

technical field [0001] The invention relates to the field of optical instruments, in particular to an 8K ultra-clear zoom visible light TV camera lens. Background technique [0002] In the upcoming 5G era, the current 8K ultra-high-definition industry is developing rapidly. However, the existing lens cannot meet the needs of normal operation in the full temperature range, and the lens structure is complex, the radial volume is large, the weight is high, the cost is high, and the information density carrying capacity is low, which cannot meet the security, medical, education, scientific research and other fields. demand. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an 8K ultra-clear zoom visible light TV camera lens, which has the characteristics of large target surface, large aperture and small distortion, and can match 8K (40 million pixels) ultra-high-definition cameras. [0004] The technical solution of the present invention is...
