47-633 25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS 0° 425-675nm

The 47-633 is a high-quality achromatic doublet lens, boasting a 25 mm diameter and an effective focal length (EFL) of 30 mm. This lens is designed for use within the visible light spectrum, specifically between 425-675 nm.

Manufactured by Edmund Optics, this lens is a multiplet, meaning it is composed of multiple optical elements. The lens is constructed from two types of Schott glass: N-BAF10 and N-SF10. These materials are known for their excellent optical properties, contributing to the lens's high performance.

The lens features a standard anti-reflection coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating is designed to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.

The lens geometry is also noteworthy. It has a thickness of 9.3 mm at the edge, with the inner and outer radii being 0. The center thickness is 11.04 mm, with an additional 3 mm of material at the center a position. The lens's base shape is circular, and it has a radius of curvature of 21.17 mm for the first surface and -16.08 mm for the second surface. The third surface has a radius of curvature of -118.66 mm.
