Plano-Convex Lenses are Optical Lenses with a positive focal length. Plano-Convex Lenses are ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries including industrial, pharmaceutical, robotics, or defense. PCX Lenses have one convex surface. For maximum efficiency, the second, plano (flat) surface should face the desired focal plane. Plano-Convex lenses are commonly used in a wide range of applications or industries.
Optical AR Coatings
a) Uncoated,The surface reflectivity of uncoated visible lenses(Refractive index＝1.5) is about 4%.
