Features
Plano-convex lens has a positive focal length, which makes it ideal for collecting and focusing light for many imaging applications.
Plano-concave lens has a negative focal length and is used for image reductinon or to spread light.
Double-convex lens has a positive focal length and is useful for 1:1 imaging and in multielement systems. also known as biconvex or equiconvex.
Double-concave lens has a negative focal length and is useful for 1:1 imaging and in multielement systems. also known as biconcave or equiconcave.
Meniscus lense has a positive or negative focal length, it forms a real or virtual image of objects.

Frequently Asked Questions
FOCtek provides plano-convex, plano-concave, double-convex, double-concave, and meniscus spheric lens forms.
Plano-convex lenses have a positive focal length, making them ideal for collecting and focusing light for many imaging applications.
Double-convex lenses have a positive focal length and are useful for 1:1 imaging and in multielement systems, while double-concave lenses have a negative focal length and are also useful for 1:1 imaging and in multielement systems.
Positive meniscus lenses have a positive focal length and form real or virtual images of objects, while negative meniscus lenses have a negative focal length and also form real or virtual images of objects.
The typical diameter tolerance for spheric lenses is +0.0/-0.2 mm for general use and +0.0/-0.02 mm for high precision use.
