LB01-12-50 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=50mm Uncoated

This is a high-quality spherical lens, specifically a double-convex lens, sourced from CeNing Optics. It is designed for use in a wide range of optical applications, thanks to its robust construction and precise specifications.

The lens has a diameter of 12.7 mm, making it suitable for use in compact optical systems. The double-convex design, characterized by two convex surfaces, provides a high degree of focusing power. The first surface radius (r1) is 51.4 mm, while the second surface radius (r2) is -51.4 mm, indicating a symmetrical design that can help minimize optical aberrations.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens has an effective focal length (EFL) of 50 mm, which is a common choice for many optical applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and uncoated lenses can be advantageous in certain situations due to their lower cost and simpler manufacturing process.
