Understanding the optics behind a PAPI light
by Victor Argueta | illumination, illumination lens design, LED, optical design
In a previous article we talked about Aviation Light Optics. and discussed a runway light system called Precision Approach Path Indicator (PAPI). Now we would like to go more in detail into PAPI design and describe their design requirements. The PAPI system...
Conoscopic Lens Design
by Victor Argueta | illumination, illumination lens design, lens design
A conoscopic lens is an instrument that can be used to measure the angular distribution of a light source. Its use is quite different from a lens, as in photography. An image created by a conoscopic lens resembles that of a fisheye lens. That is a...
Projection Lens Design
by Victor Argueta | illumination lens design, lens design, optical design, Zemax
Projection systems are one of the most common consumer optical devices (probably second to photographic systems). They allow us to view images on a screen (usually) by magnifying and projecting them at distances from a few centimeters to several meters away...

What is a rayset (rayfile) ?
by John | illumination lens design
A ray set is a optical model showing the path of millions of rays of light existing a source such as an LED
