BST biconvex lens Introduction: A biconvex lens has two convex surfaces with equal curvature, a positive focal length, and is more suitable for applications in 1:1 imaging and multi component systems. A biconvex lens is most suitable for situations where the object and image are on both sides of the lens, and the ratio of image distance to object distance (conjugation ratio) is between 0.2 and 5. The product with coating has better transmittance. Technical parameters: Materials: optical glass and silicon, germanium, zinc selenide, zinc sulfide, fluoride, sapphire Diameter tolerance:+0/-0.01~+0/-0.1mm Thickness tolerance: ± 0.01~± 0.1mm Face type: λ/ 10~ λ/ 2@632.8nm Finish: 10/5~60/40 Eccentricity:<30 "~3 ' Effective aperture:>90% Chamfer: Coating: antireflective film, bandwidth antireflective film
