Description

Double convex lens

Double-Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCX Lenses are used in a range of industries or applications.

Optical AR Coatings

a) Uncoated,The surface reflectivity of uncoated visible lenses(Refractive index＝1.5) is about 4%.

b) AR/AR@400-700nm,Tavg>99.4%

c) AR/AR@450-650nm,Tavg>99.6%

d) AR/AR@400-1000nm,Tavg>98.5%

e) We can also customize high damage threshold antireflective coatings
