BARRINGTON, N.J., Jan. 18, 2011 — Edmund Optics has introduced two liquid-filled lenses from Optotune Inc. The tunable polymer electrically focused and manually focused lenses replace multiple optical elements. They can replace the functionality of a complete lens kit, eliminating the complex alignment and optomechanical issues associated with multilens systems.

The electrically focused models provide a single-lens solution for focus and zoom objectives. When the user applies a voltage to each compact planoconvex lens, the lens changes effective focal length. Each lens is filled with an optical liquid, and the change in voltage alters the pressure profile of the liquid, resulting in a change in radius of curvature. This electrical manipulation of the radius allows for a focal range of 15 to 100 mm and an aperture of 10 mm. The robust lenses are available in high-refractive-index or low-dispersion options for research and for OEM integration. Cover glasses are available with either a VIS or NIR coating.

The manually focused models use a rotating outer ring to manipulate their focus length and change the shape of the lens from convex to concave. Using liquid-filled lens technology, they offer a wide focal tuning range of -40 to 40 mm. With a large aperture diameter of 20 mm, they are suitable for use in education and research applications and in lighting systems, where the option to adjust the focal length allows for expanded control of the light source. The durable lenses are available in high refractive or low dispersion options. Cover glasses are available with a VIS coating.

The lenses provide continuous focusability over a specific focal range, permitting the user to custom-tune them. With a wide variety of materials and coating options, they offer the focal adaptability and versatility that accommodate numerous research and OEM applications. Lenses are in-stock and available for immediate delivery.
