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%.

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
