49-771 12.7 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=15mm VIS 0° 425-675nm

The 49-771 is a high-quality achromatic doublet lens, boasting a 12.7 mm diameter and an effective focal length (EFL) of 15mm. This lens is designed for use within the visible light spectrum, specifically between 425-675nm.

The lens is composed of two elements: N-BAF10 and N-SF57, both from the reputable Schott glass catalog. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.

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 enhances light transmission while reducing unwanted reflections, thereby improving the overall efficiency and image quality of the optical system.

The geometry of the lens is meticulously designed, with a center thickness of 6.5mm and edge thickness of 5.72mm. The lens curvature is also precisely controlled, with radii of 10.59mm and -8.26mm for the first and second surfaces, respectively, and an additional -30.7mm for the third surface.
