High Presion Double Convex Lenses and Bi-convex Lenses
Double Convex Lenses(Bi-convex Lenses) have two outward curved surfaces, a positive focal length and are useful for 1:1 imaging and in multi-element systems.These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1)).
1. Supported by the Zemax Optical Design Package
2. Posistive Focal Length
3. Material upon requirement
WTS offer customize Double Convex Lenses products.

Double-Convex
lenses have the same radius of curvature on both sides of the lens and
function similarly to plano-convex lenses by focusing parallel rays of
light to a single point. As a guideline, double convex lenses perform
with minimum aberration at conjugate ratios between 5:1 and 1:5.
