Continuous zoom lens with magnification adjustment indicating device

Abstract

A continuous zoom lens with a magnification adjustment indicating device comprises a position detection signal transmitting and receiving device, a position detection signal reflecting device, a decoding communication device and an indicating device. The continuous zoom lens overcomes the defect that whether a lens in magnification adjustment is adjusted to an accuracy position with a current target magnification or not cannot be known during magnification change of a continuous zoom lens in the prior art. The continuous zoom lens with the magnification adjustment indicating device is capable of sending signals in real time to indicate whether a manual continuous zoom lens is adjusted to the accurate position with the current target magnification or not and is precise in positioning, detection precision of an application detecting mechanism of the continuous zoom lens is improved, and operating efficiency of the application detecting mechanism of the continuous zoom lens is further improved by directly acquiring information through indication signals.

Description

technical field [0001] The invention relates to a continuous zoom lens, in particular to a continuous zoom lens equipped with a magnification adjustment indicating device. Background technique [0002] With the rapid development of optical technology and the continuous expansion of its practical application range, the demand for continuously zooming optical systems is increasing. At present, the continuous zoom lens is widely used in the fields of biology, medicine, environmental protection, materials, public security criminal investigation, monitoring, microelectronics and precision processing. Specifically, the zoom lens is provided as a main component for microscopes, video microscopy systems, automatic detection systems, and surveying and mapping instruments. [0003] When the lens is used, it is necessary to select a suitable magnification in real time for the specific subject and its environment, which is called zooming, in order to obtain high-resolution and high-def...
