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.
A plano-convex lens has a positive focal length and is ideal for collecting and focusing light, while a plano-concave lens has a negative focal length and is used for image reduction or to spread light.
A double-convex lens has a positive focal length and is useful for 1:1 imaging and in multielement systems, while a double-concave lens has a negative focal length and is also useful for 1:1 imaging and in multielement systems.
A meniscus lens has a positive or negative focal length and forms a real or virtual image of objects. Its applications include laser optics, metrology, OEM, industrial, and spectrometry.
