Optical Plano Concave Lens
Plano-Concave Lenses are ideal for beam expansion, light projection, or for expanding an optical system’s focal length. Plano-Concave Lenses, which have one concave surface, are Optical Lenses with negative focal lengths. PCV Lenses should be oriented with the plano, or flat, surface towards the desired focal plane. PCV Lenses are ideal for use in a range of applications or industries.
Plano-Concave (PCV) lenses have one flat and one inward curved surface. PCV lenses have a negative focal length and are used for image reduction or to spread light.
Optical AR Coating
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
