This study is about processing thermal infrared ray camera with a single lens using germanium, and AR coating. OSLO is used for optical design, structure is designed with Auto CAD, Solidworks and DTM is used to process the lens. It now is possible to have a smaller thermal infrared ray camera that have same performance with exciting thermal infrared ray cameras.

This study is aimed to develop micrimini telephoto optical system using board camera. Spheric glass lenses and aspheric mirrors are used to complement limits of telephoto efficiency in existing board camera optical system. Further more a new optical market may be opened because inaccessible place such as natural disasters and industrial accidents can be observed.

This study's goal is developing modules of LED lighting for multi expandable Downlight. We are making it as occasion demands multi expandable, compact, kept reduced glaring and even light uniformity compared with existing LED lighting for Downlight by developing aspheric lens shaped sheets. Now we finished a design and a simulation, and we are developing Mock-up.

Because of having ununiformity and unstability, there was no way to find out property of light from previous surface light source. This paper showed the approach of new solution to improve nature of light diffuse. We secure credibility of uniformity for LED Chip and derived the standardizing conclusion through of simulation using the approach of new solution.
