Optical manufacturing and testing is the process of manufacturing and testing optical components. It spans a wide range of manufacturing procedures and optical test configurations. The manufacture of a conventional spherical lens typically begins with the generation of the optic's rough shape by grinding a glass blank. [1]
Thorlabs, Inc. is an American privately held optical equipment company headquartered in Newton, New Jersey. [2] The company was founded in 1989 by Alex Cable, who serves as its current CEO. His daughter, Jennifer Cable, serves as president. [3] As of 2018, Thorlabs has annual sales of approximately $500 million. [4]
Köhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy.Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image.
An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. Common examples include periscopes , microscopes , telescopes , and cameras .
Its sister publication is Restaurant Development & Design, which was launched in 2012. [2] Foodservice Equipment & Supplies' Dealer of the Year award was recognized as the pre-eminent honor in foodservice distribution. This award dated back nearly a quarter of a century and recognized the industry's most outstanding equipment and supplies ...
After many years as rivals, Essel and Silor merged on 1 January 1972 to form Essilor, then the world's third-largest ophthalmic optical firm. [1] Its first year of existence was marked by the creation of Valoptec, a non-trading company composed of stockholder managers who held half the company's capital stock, and the purchase of Benoist-Bethiot, a French lens manufacturer specializing in ...
Optical engineering is the field of engineering encompassing the physical phenomena and technologies associated with the generation, transmission, manipulation, detection, and utilization of light. [2] Optical engineers use the science of optics to solve problems and to design and build devices that make light do something useful. [3]
On the tool surface, highly adherent thin coatings are synthesized. Materials for coatings on optical inserts are Platinum-based PVD (mostly iridium-alloyed, standard), diamond-like carbon (not yet commercially available), SiC (CVD) on SiC-ceramics (not yet commercially available, have to be post-machined) or TiAlN (not yet commercially available).
