Frequently Asked Questions

FOCtek provides five kinds of spheric lens forms, or shapes, that determine the imaging characteristics of the lenses. They are plano-convex, plano-concave, double-convex, double-concave, and meniscus.

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 reduction or to spread light.

Double-convex lens has a positive focal length and is useful for 1:1 imaging and in multielement systems. It is 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. It is also known as biconcave or equiconcave.

Meniscus lens has a positive or negative focal length, and it forms a real or virtual image of objects.
