Product Description

Biconvex lenses also known as double convex lenses are simple optical lenses with two convex spherical surfaces, surfaces which bulge out from the center. These two convex surfaces have the same radius of curvature, and the lens focuses parallel rays of light to a single point beyond the lens. Double convex lenses play an important part in many imaging devices such as microscopes, cameras, telescopes, image relays. They are used to focus and control laser beams, and in telecom IR applications. At DG Optics we manufacture high quality biconvex lenses, both coated and uncoated, for a wide range of beam-focusing applications.Detailed PhotosProduct Parameters

Basic processing technoiogy:
The first: milling is to remove uneven bubbles and impurities on the surface of the lens, which plays a moulding role (about 0.05-0.08).The second: fine grinding is to eliminate the damaged layer of the milled lens and fix the R value.The third: polishing is to polish the polished lenses again. This process is mainly to make the appearance better.The Fourth: Cleaning is to clean the polished lens clean the polishing powder on its surface to prevent compression.The fifth: grinding edges is to grind the original lens outer diameter to the specified outer diameter.The Sixth: Coating is a coloured film or other film that will be coated with one or more layers of lenses that need to be coated.The Seventh: Ink coating is a layer of black ink that will require lenses to prevent reflection from being reflected on its outer edge map.The Eighth: Gluing is to glue two lenses with opposite R values of the same size as the outer diameter.
