Request InfoSigma Corp. of AmericaThe 135-mm ƒ1.8 DG HSM Art Lens from Sigma Corp. of America is a mid-range telephoto prime lens with a greater shallow depth of field and isolation of subjects. A compression effect makes it equally as powerful for up-close and full-length portraits. Its Hyper Sonic Motor delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds and for fast autofocus photography. Top performance is provided from the center to the edges of the image due to the signature floating system of the lens focus mechanism.

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 HandbookDigital Still Cameras: The Changing Face of Imaging: The digital camera reflects a sea change in the compact camera market. While the 20th was the century of film cameras, the 21st belongs to the digital camera.The digital camera represents an integration of optics, mechanics and electronics consisting of three layers (Figures 1a, b and c). The top and the middle layers are printed circuit boards (PCBs),...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. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookComponent Choices: Avoiding Tolerancing Mistakes: Designing an optical system involves more than simply understanding the theory behind optics. To design a system efficiently and economically, it is important to understand the capabilities of an optical shop and the interaction of the specifications involved in ordering and designing components.To the novice or casual user of optics, the acquisition of an optical system can be a very difficult experience.
