LA1470 N-BK7 Plano-Convex Lens; Dia:6.0 mm; f=12.0 mm Uncoated

The LA1470 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 6.0 mm, is designed for use in a variety of optical systems, offering a focal length of 12.0 mm for precise focusing and imaging capabilities.

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 applications due to its low coefficient of thermal expansion and high homogeneity. The plano-convex design of the lens, where one side is flat and the other is curved, allows for efficient light collection and transmission.

The geometry of the lens includes a thickness of 1.5 mm at the edge and 2.3 mm at the center, providing a solid structure while maintaining a compact profile. The effective focal length (EFL) of 12.0 mm, combined with a radius of curvature of 6.2 mm, ensures a wide field of view and low distortion. The back focal length (BFL) is 10.5 mm, which is crucial for determining the lens's position in an optical system.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide excellent performance in many applications, especially when the light source has a low power or when the system does not require high contrast or low reflection.
