Request InfoEdmund Optics Inc.BARRINGTON, N.J., March 14, 2012 — Edmund Optics has introduced its TechSpec high-contrast plastic linear polarizers, which it says are more durable than polarizing film The devices feature a good extinction ratio and high transmission of unpolarized light from 400 to 700 nm. They improve contrast by reducing glare, and eliminating glare is critical in imaging applications where high contrast is essential, including edge detection and when used with cameras employing small-aperture lenses. They are suited for a variety of imaging applications.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
