Product Details
Our A-25H Variable Focus Lens is an excellent fit for low footprint systems requiring fast response time and large focusing range, and is especially suitable for miniature industrial cameras. It provides a fast-track to market for product designers who need an easy to integrate, high-performance auto focus solution.
A-25H is based on Corning Varioptic’s breakthrough lens technology, allowing variable focus with absolutely no moving parts.
The A-25H lens is broadly suited for standard imaging applications. For very close distance imaging needs, the A-25H-D0 is specially designed with a high dynamic range.
A-25H comes with two different AR coating options and also in a pre-packaged type, with straight or bent FPC connection.
