optical requirements for roadway lighting, ranked

All roadway lamps must be designed according to specific standards. The most popular ones are a US standard called “IESNA RP 8-00 Roadway lightning” and a European one called “CIE 140-2000 Road lighting calculations”. In the case of CIE 140-2000, the standard only specifies parameter definitions, calculations, and measuring technique, while the actual parameter values […]

Infrared and thermal imaging design

Infrared and thermal imaging design

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 0.75-1000 µm wavelength band. This spectral region is divided into five intervals: Thermal imaging IR-radiation has a […]

Scanning and Fluorescent Microscope Design Steps

Scanning and Fluorescent Microscope Design Steps

Microscopy is a fundamental technique used to analyze samples that are too small to be perceived without magnification. It is used in multiple sciences, from biology, medicine, chemistry to anthropology, and any science where small samples are presented. Early microscopes were simple instruments with just a couple of optical elements. As methods improved, so did […]
