I got my hands on a piece of photo history, namely, the technical documents that describe the design of the Soviet-era Tair-3 ...

Methods are presented for using two-dimensional (axially symmetric) aperture lenses of both the single- and multiaperture (fly's-eye) kind and one-dimensional (planar-symmetric) aperture lenses in ...

Thypoch has unveiled its most dramatic wide-angle yet – the Simera 21mm f/1.4 Leica M lens. This new addition to the Simera ...

In this study, we have demonstrated a versatile and low-cost nanofabrication method referred to as “angled nanospherical-lens lithography (A-NLL)”, which is able to produce large-scale and periodic ...

If you have ever played around with lenses, you’ll know that a convex lens can focus an image onto a target. It can be as simple as focusing the sun with a magnifying glass to b ...

We report the first fabrication and development of a deep phase Fresnel lens (PFL) in silicon through the use of gray-scale lithography and deep-reactive ion etching (DRIE). A Gaussian tail ...

A novel method to produce sub-microwalled chemically activated polymer microwells by one-step UV-lithography under ambient conditions which are selectively coated with gelatin is introduced. The ...

The innovative optical design and incorporation of aspherical elements enable the new SL-Lens to deliver exceptional performance while maintaining a constant f/2.8 aperture across its entire ...
