Lens has many applications ranging from simple convergence or divergence of laser beam to precise imaging and image transfer.
THATSHIGH provides diverse lenses for different applications.
Lens | Materials | Illustration | 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. |
