Product Family Description

Optotune Electrically Focus-Tunable Lenses offer a single-lens solution for focus and zoom objectives. Applying a control current to each compact, plano-convex lens changes their radius. Electrical manipulation of the radius allows for a focal range of +50 to +120mm, providing an adjustable focal length for a variety of purposes and negating the need for a multi-lens system. The cover glasses are available with VIS or NIR coating.

These tunable lenses can replace the functionality of a complete lens kit in laboratory settings, offering the on-demand adaptability needed to avoid the complex mechanical manipulation associated with a multi-lens system. Ideal for researchers and OEMs alike, Focus-Tunable Lenses offer continuous focusability over a specific focal range, allowing the user to custom-tune the lenses for optimum performance. Available in a variety of coating options, the focal adaptability of the Optotune Electrically Focus-Tunable Lenses make them ideal for a range of applications where versatility is preferred.
