Introduction Optical invariants serve as invaluable mathematical representations encapsulating various optical parameters within an optical system. Despite the dynamic nature of optical components, these invariants remain constant, providing a stable foundation amidst...
There are two primary methods of image formation in lens design. Perspective projection (F-Tan Theta lenses also called Rectilinear or Orthoscopic). Equidistant projection (F-Theta lenses also called Equiangular) The Perspective projection method is most often used...
In the coming weeks, we will be posting about the unique design considerations and material requirements for infrared optical systems. In this post, we will focus on the definitions optical engineers use. Infrared radiation includes electromagnetic waves with...
