Plano Convex Spherical Lens

Question

·Plano-convex is close to best from for a focusing lens

 

 

·Focusing or optical imaging

 

 

 

 

 

 

Plano-convex lenses are useful for a wide range of applications. These lenses are manufactured from  BK7A, UV FS, IR FS, IR CaF2, UV CaF2, ZnSe, All lenses are uncoated but Anti-reflection coatings are available. When used to focus a collimated beam, the light should be incident on the curved surface of the lens. These plano-convex lenses may be combined with other lenses to form complex imaging systems.\
