Background

The field lens is a lens which works near the focal plane of the objective lens and can effectively reduce the size of the detector. The field lens can be divided into a flat field lens and a telecentric field lens according to functions. The telecentric field lens is designed mainly for eliminating phase difference, can ensure that the magnification of the obtained image is not changed within a certain object distance range, and is mainly applied to machine vision occasions with high requirements on lens distortion. A telecentric field lens causes the chief rays of the focused beam to be perpendicular to the focal plane at any field angle by having the system's entrance pupil at the front focal position of the lens system. After the telecentric field lens is installed, the height of the lens base is inconvenient to adjust, so that the telecentric field lens can only work at a fixed height, the focusing range of the telecentric field lens on light beams is limited, and the telecentric field lens is not beneficial to focusing.
