Tailored Distortion®: Distortion Correction at the Speed of Light
Super wide-angle lenses and fisheye lenses have pronounced barrel distortion. When viewing a flat object, off-axis features are “squeezed” significantly relative to the on-axis ones.

Certain applications require a broad spectral operating range and customers oftentimes inquire whether a lens can perform “well” out to their wavelength of interest. These
The imaging applications in the automotive industry go through rapid changes. Where just a couple of years ago a lens/camera just needed to survive, the
“Scaling’ refers to a method where a known lens design is proportionally enlarged or reduced geometrically to meet a different image size requirement from what
With the advent of computers and more processing power, the art of lens design has matured. But computers cannot solve the whole problem. A computer
One of the most common questions Sunex receives is regarding the need for Active Alignment of lens modules. Initially, customers designing or prototyping an imaging
Many customers use Sunex lenses in a custom housing unit which is unique to their particular application. In many wide-angle lenses, especially fisheye lenses, it
At Sunex, we get the above question frequently, but the answer is not straightforward. Specifying an operating temperature range for a lens can be tricky,
Sunex Inc. has developed design expertise, process know-how, and manufacturing facilities to eliminate or minimize optical noise (such as ghosts, flare, starbursts, spurious images) in
Following up on the article Optical Tolerances – Part 1, Part 2 discusses the quantitative measure of image quality. The modulation transfer function (MTF) is
