Property and Application |
|
Plano-convex |
BK7 |
|
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 |
|
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 |
|
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 |
|
Negative lens with the form most suitable for producing diverging light or virtual image, when the input light is converging. |
