MANUFACTURING FRESNEL LENSES. The first Fresnel lenses were made by tediously grinding and polishing glass by hand. Eventually, molten glass was poured into molds, but it was only with the development of opticalquality plastics and injectionmolding technology in the 20 thcentury that the use of Fresnel lenses in many industrial and commercial appliions became practical.

In order to understand optical specifiions, it is important to first review what they mean. To simplify the evergrowing number, consider the most common manufacturing, surface, and material specifiions for lenses, mirrors, and windows. Filters, polarizers, prisms, beamsplitters, gratings, and fiber optics also share many of these optical ...

The surface of a metallographic specimen is prepared by various methods of grinding, polishing, and preparation, it is often analyzed using optical or electron only metallographic techniques, a skilled technician can identify alloys and predict material properties.. Mechanical preparation is the most common preparation method.
Optics basics. The basic purpose of a lens of any kind is to collect the light stered by an object and recreate an image of the object on a lightsensitive 'sensor' (usually CCD or CMOS based). A certain number of parameters must be considered when choosing optics, depending on the area that must be imaged (field of view), the thickness ...
