G063852000 25.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=50mm Uncoated

The G063852000 is a 25.4 mm diameter, double-convex lens with a mount, sourced from Qioptiq Photonics. This lens is designed for use in the visible light spectrum, specifically at a wavelength of 587.6 nm. The lens is made from N-BK7, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion.

The lens features a large diameter of 25.4 mm, providing a wide field of view. It has an effective focal length (EFL) of 50 mm, making it suitable for a variety of applications that require moderate magnification. The lens is uncoated, meaning it does not have any anti-reflective coatings. This can result in higher reflective losses at the air-glass interfaces, but it also means the lens is less susceptible to damage from environmental conditions.

The lens geometry is spherical, with both surfaces curved outwards. The first surface has a radius of curvature of 51.08 mm, while the second surface has a radius of curvature of -51.08 mm. This double-convex design provides a strong focusing power, but it can also introduce spherical aberration. The lens thickness at the edge is 3.8 mm, while at the center it is 7 mm. The lens does not have any inner or outer radii, indicating it is a simple, symmetric lens.
