LA1259 N-BK7 Plano-Convex Lens; Dia:1 in; f=2500.0 mm Uncoated

The LA1259 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 1 inch, is designed for use in a variety of optical systems, offering a focal length of 2500.0 mm, making it suitable for applications that require long focal lengths.

The lens is made of 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's geometry is spherical, with a plano-convex shape, meaning one side is flat while the other is curved. This design is commonly used in optical systems due to its ability to focus light to a single point.

The lens's geometry includes a diameter of 25.4 mm, with a thickness of 2 mm at the edge and 2.1 mm at the center. The effective focal length (EFL) is 2500.0 mm, and the radius of curvature (R1) is 1292 mm. The back focal length (BFL) is 2498.6 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While coatings can enhance the performance of optical components in certain applications, uncoated lenses like the LA1259 can be suitable for applications where such enhancements are not necessary.
