AI Technical Summary
Existing industrial lenses have high requirements for resolution at the edge of the field of view, and it is difficult to guarantee the consistency of resolution at different object distances. Furthermore, large aperture distortion is difficult to control, resulting in poor image quality.
An industrial lens is designed by using a combination of seven spherical and aspherical lenses, and by rationally allocating optical power and front-group focusing methods through the allocation of lens materials. The lens includes a lens assembly arranged sequentially from the object side to the image side along the optical axis, with the fourth and fifth lenses cemented together to form a cemented lens, satisfying specific optical parameter relationships.
It achieves high-resolution focused imaging within an object distance range of 100mm to 1000mm, with a maximum optical distortion of less than 0.20% and an imaging quality of 200pl/mm>0.45MTF, balancing a large aperture and low distortion.
