Technical Field

Background
In order to ensure the quality of the produced optical lens, the produced optical lens is usually debugged and inspected to ensure the outgoing quality of the lens. However, the detection devices in the prior art generally have the problems of difficult focusing and difficult movement.
In particular, a micro-photography lens is different from other lenses, because the micro-photography lens defines the magnification, the micro-photography lens does not have focusing, and a common debugging instrument is difficult to accurately position an in-focus point during image adjustment. The prior art methods for locating the focus point include the following two methods:
(1) the moving target plate is difficult to find due to the large magnification of the micro-photographic lens, so that the accurate focusing can be realized only by taking a long time, and the efficiency is low;
(2) the moving debugging instrument has the same problem as the moving target board, the target is difficult to find due to slight movement, the accurate focusing can be realized only by taking a long time, the efficiency is low, the instrument is heavy, and the moving is inconvenient.
Moreover, because the lens of photomicrography is longer heavier, when with the bayonet socket connection in the check out test set (ordinary image modulation instrument is all the daily shooting custom of simulation human, the level is placed), because the weight of lens self, easily down the skew, influence the image quality.
The length of the lens with different multiplying powers is inconsistent, and the position of the light source in the common image adjusting instrument is fixed and unchangeable, so that the lens with different multiplying powers is not suitable for the lens with different multiplying powers. If the image adjusting instrument in the prior art is adopted to detect the lenses with different magnifications, different image adjusting instruments are required to be used, such as: if the lenses with four different magnifications are to be detected, four image adjusting instruments with different specifications are needed.
The common image adjusting instrument is projected on the front curtain wall, although the common image adjusting instrument can meet the detection that the central line pair is 160 line pairs of the common photographic lens, the target plate used by the microscopic photographic lens is 1600 line pairs, and the mode of projecting the common image adjusting instrument on the front curtain wall cannot meet the detection requirement because the naked eyes cannot visually observe whether the image is clear or not.
