Property and Application

Plano-convex

BK7
Fused Silica
CaF2

Lens

Positive focus length. Most suitable in conditions where one conjugate is five times more than the other, e.g. in sensor application or for use with near collimated light.

Double-convex

BK7
Fused Silica
CaF2

Lens

Most suitable in conditions where the conjugates are on opposite sides of the lense and the ratio of the distances is less than 5:1, e.g. as simple image relay components.

Plano-concave

BK7
Fused Silica
CaF2

Lens

Negative lens with the form most suitable in conditions where one conjugates is five times more than the other, e.g. producing divergent light from a collimated input beam.

Double-concave

BK7
Fused Silica
CaF2

Lens

Negative lens with the form most suitable for producing diverging light or virtual image, when the input light is converging.
