Codex International has introduced custom lenses and windows made from zinc selenide, zinc sulfide, fused silica, germanium, silicon, and other materials for a myriad of applications.
Codex Internaitonal can be supplied plano-convex, plano-concave, and as wedged-windows in round, rectangle, and square shapes that can include steps, holes, and other special features. Made from ZnSe, ZnS, fused silica, germanium, silicon, and other materials, they are well suited for laser, imaging system, machine vision, and opto-mechanical applications.
Manufactured in sizes from 0.5″ to 5″ O.D. and supplied with various A/R coatings, as required, Codex Internaitonal Optics can be fabricated in a variety of thicknesses with typical dimensional tolerances of ±0.001 to ±0.005″. Conforming to ISO-10110 specifications, surface finishes of 10 waves to 1/10th wave flatness and 10-5 to 80-50 scratch-dig can be provided.applications.
Thin films are thin coating layers present in many different technologies. Despite their widespread use, most of the focus is around how they provide a barrier to various stimuli, or how they can be used as a conductive medium. However, there is another class of thin films that we will discuss, and these are optical thin films.Lire la suite
Optical crystallography is the branch of science that focuses on the optical properties of crystals. Also known as crystal optics, it describes the behavior of light in anisotropic media, such as crystals, in which the light behaves differently depending on which direction the light is traveling.Lire la suite
