Continuing advances in high-resolution sensors with higher pixel densities and smaller pixels are challenging optics manufacturers to produce lenses with increased performance. To understand how lenses can affect the performance of imaging systems, it is necessary to grasp the physics behind diffraction, lens aperture, focal length, and the wavelength of light.

In the last few years, the techniques of noncontact optical measuring technology have experienced a tremendously rapid increase. This has come about, in the first place, because the use of electronic image processing has made it possible to automate whole chains of processes. In the wake of this development, the object-side telecentric lenses have become more and more widely accepted. Their ability to form an image independent of its distance, but always with the same size, is the basic precondition for a successful automatized measurement process. While object-sided telecentrics moved into the center of attention, the image side, i.e., the area between the lens and the camera, disappeared almost completely from view. At the same time, the organization of this side is just as important for highly exact measurement technology as that of the object side.
