Overview
Product Details
High precision custom optical glass K9 BK7 double convex optical lens
PRODUCT DESCRIPTION
Optical lenses are designed to focus or diverge light, they can be made of a single piece of glass or have multiple elements.Surfaces of optical lenses may be spherical, aspheric or cylindrical. Optical lenses are widely used in a variety of applications, from life science, laser processing and imaging, to medical, security and defence industries. While Plano-Convex (PCX) or Double-Convex (DCX) lenses focus light to a point, the Plano-Concave or Double-Concave (DCV) lenses are designed to diverge light. Achromatic lenses are used to correct chromatic aberration, and aspheric lenses are designed to correct the aberration from spherical shape.
