N-Bk7 Bi-Convex Lenses/N-Bk7 Biconvex Lens/Bk7 Bi-Convex Lens

Description

General Introduction: Raytek biconvex lens is usually used for focusing applications, and is the best choice when the distance between the object and the imaging lens is equal or close. These biconvex lenses have an exact convex surface at both ends.
Raytek's n-bk7 biconvex lens can choose not to be coated, but also to be coated with a variety of multilayer antireflective coatings. All lenses are guaranteed λ/ 4 surface accuracy and 40-20 scratch-dig surface quality. N-bk7 is an excellent lens material for most visible and near infrared applications. It has high homogeneity, low content of bubbles and inclusions, simple and direct manufacture, and can provide excellent performance with economic cost.
