The realization of the large aperture for 2.74µm pixel size, 1.1'' sensor diagonal and stable imaging performance for various wavelengths has greatly increased the requirements for magnifying telecentric lenses. Adding a focus tunable liquid lens while maintaining imaging performance has been a challenge, but Sill Optics and Optotune have achieved 90 lp/mm resolution across the entire FOV using an EL16-40 with best wavefront specification in vertical alignment.
This enables the lens to provide outstanding performance for a 2x magnification telecentric lens for sensors with 12-20 megapixels with additional automated focus adjustment of at least 6mm. This product paves new ways for the fields of semiconductor inspection and precision metrology to reach milestones.
