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 reduction or to spread light.
- Double-convex lens has a positive focal length and is useful for 1:1 imaging and in multi-element systems. also known as biconvex or equiconvex.
- Double-concave lens has a negative focal length and is useful for 1:1 imaging and in multi-element systems. also known as biconcave or equiconcave.
- Meniscus lens has a positive or negative focal length, it forms a real or virtual image of objects.

Frequently Asked Questions
Double-convex lenses have a positive focal length and are useful for 1:1 imaging and in multi-element systems, while Double-concave lenses have a negative focal length and are useful for 1:1 imaging and in multi-element systems.
Crysmit provides five kinds of lens forms for spheric lenses, namely Plano-convex, Plano-concave, Double-convex, Double-concave, and Meniscus.
Plano-convex lenses have a positive focal length, making them ideal for collecting and focusing light for many imaging applications.
Meniscus lenses have a positive or negative focal length and can form a real or virtual image of objects.
Plano-concave lenses have a negative focal length and are used for image reduction or to spread light.
