Boresight Stabilization™

Marketing Team

A typical lens assembly consists of several lens elements inside a cylindrical barrel.  Due to the mechanical clearance requirement, the internal element diameters must be smaller than the barrel internal diameter. This creates potential risks that could result in boresight errors or changes: Lens to lens variance of the optical axis due to manufacturing tolerance A possible lateral shift of individual elements overtime due to strenuous conditions The first potential risk (lens to lens variance)…

Lens Image Circle

Technical Team

One of the most important specifications for an imaging lens is the image circle. So what is the image circle of a lens ? This question is often asked without a clearly definition of the image circle. This article will attempt to clarify the concept of image circle and discuss what’s to be expected from real-world lenses in terms of image circle. When a lens is first designed the designer must choose a maximum field…
