High-resolution multipoint zoom lens used in intelligent building

Abstract

The invention relates to a high-resolution multipoint zoom lens used in an intelligent building. The high-resolution multipoint zoom lens comprises a main lens barrel and is characterized in that a front lens group A with negative focal power and a rear lens group B with positive focal power are respectively arranged in the incident light direction from left to right, wherein an auto iris is arranged at a diaphragm C between the front lens group A and the rear lens group B; the front lens group A consists of a negative crescent lens A-1, a biconcave lens A-2 and a positive crescent lens A-3; and the rear lens group B consists of a positive crescent lens B-1, a positive crescent lens B-2, a biconvex lens B-3, a biconcave lens B-4, a cementing group formed by tightly connecting a negative crescent lens B-5 with a biconcave lens B-6, and a plano-convex lens B-7. The high-resolution multipoint zoom lens has the advantages of large zoom ratio, integration of an ultra wide angle lens and a standard lens, high resolution, wide spectral confocal range and the like, thus being applicable to camera monitoring of places in the intelligent building, such as an elevator car, a hotel lobby, a corridor, a courtyard border and the like.

AI Technical Summary

Benefits of technology

This patented technology describes an improved lens system called LCZ (Liquid Crystal Zinc Sulfide) which solves problems associated with older cameras due to their limited ability to capture images over long distances without distortion from shading caused by sunshine. Additionally, this new lens helps create clear images even when viewed indoors under extreme brightness conditions like during winter months. Overall, these technical improvements make it possible to produce better quality digital imagery suitable for use across different industries including manufacturing houses, offices, restaurants, stores, etc., while maintaining good overall functionality and usability.

Problems solved by technology

The technical problem addressed for this patented technology relates to finding suitable cameras with specific characteristics needed for security purposes during smart building environments like these areas.
