產品名稱 : Ø12.7mm Lenses, EFL. 20 ~ 20000mm
產品說明 :
Plano-convex lenses are useful for a wide range of applications. These lenses are manufactured from BK7A for visible and Near IR applications. 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.
