Project Overview
The focal point of this project involves crafting an optical system tailored to the customer’s specifications, with wavelengths exceeding 500mm, and featuring exceptionally petite double-convex aspheric lenses (diameters less than 3mm). To enhance performance, we implemented designs using N-BK7 or N-SF11, capitalizing on the distinctive properties of these materials. Notably, our design diverges, contributed by cost reduction through the use of N-BK7 or N-SF11, from conventional approaches to double-convex aspheric lenses. Ultimately, we effectively fulfilled the customer’s demands, achieving an underwater focus of less than 10mm.
