Optical Element
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.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
