Transmissives include lenses, filters, windows, optical flats, prisms, polarizers, beamsplitters, wave plates, and fiber optics; reflectives include mirrors and retroreflectors. The performance of all may be enhanced with certain substrates and thin film coatings.Lenses come in a variety of shapes, sizes and materials. They can be made of a single piece of glass or have multiple elements; their surfaces can be spherical, aspheric or cylindrical; they can be...Photonics HandbookMeasuring Aspheres: Selecting the Best Technique: The metrology method should match the nature of the part and the inspection constraints.The benefits of aspheric lenses are numerous: They allow for a reduction in spherical aberrations and are ideal for focusing or collimating light, as they can achieve a low ƒ-number. Aspheres...Photonics HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market.
