The first summar lens, a simple convex glass, revolutionized photography by allowing for sharper images. However, even with this breakthrough, the precision of lens manufacturing was far from perfect. Today, a surprising number of lenses exhibit decentering, a condition where the optical axis is not perfectly aligned with the mechanical axis.

What percentage of camera lenses are decentered remains a topic of debate, but even a slight misalignment can affect image quality. Fortunately, the precision of modern lens manufacturing has significantly reduced the prevalence of decentering, ensuring that the legacy of the first summar lens lives on in the high-quality images we capture today.

Working Principle of Summar Lenses

Summar lenses, also known as telecentric lenses, are specialized optical systems designed to capture images with a uniform magnification across the entire field of view. These lenses are widely used in various applications, including machine vision, metrology, and microscopy, where precise measurements and accurate image representation are crucial.

The unique working principle of summar lenses is rooted in the specific arrangement of optical elements and the way they interact with light.

Light Refraction and Convergence

The core of summar lens functionality lies in the careful design of its lens elements and their arrangement. The lens system typically comprises multiple lenses, often with a telecentric stop positioned at the lens’s rear focal plane. This stop ensures that all light rays entering the lens system are parallel to the optical axis before they reach the image plane.

The telecentric stop acts as a virtual aperture, limiting the light rays passing through the lens to those that are parallel to the optical axis.This unique arrangement ensures that all light rays entering the lens system converge at a single point on the image plane, regardless of their point of origin within the field of view.

This characteristic eliminates image distortion and maintains consistent magnification across the entire image. The telecentric stop effectively eliminates the perspective effect, resulting in an image that is a true representation of the object’s size and shape, irrespective of its distance from the lens.
