In a previous article we talked about Aviation Light Optics. In that article we talked about the Precision Approach Path Indicator (PAPI). Now we would like to go more in detail about that system and describe their design requirements. The PAPI system is a...
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 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...

A rayset (sometimes called a rayfile) is a key element in the design of any illumination system. It describes the path of hundreds of thousands, millions, and even billions of rays of light as they leave a source (typically an LED). This data set is used in a ray...
