产品描述

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 Fused Silica CaF2		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		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		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		Negative lens with the form most suitable for producing diverging light or virtual image, when the input light is converging.
