LA1270 N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=25.0 mm Uncoated

The LA1270 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 18.0 mm, is designed for use in a wide range of optical systems, offering a focal length of 25.0 mm.

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 geometry of the lens, where one side is flat and the other is curved, is a common design for collimating or focusing light in various optical systems.

The geometry of the LA1270 lens includes a thickness of 1.8 mm at the edge and 5.5 mm at the center. The radius of curvature of the curved surface is 12.9 mm, and the back focal length is 21.3 mm. The 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 where cost or simplicity are considerations.

This lens is suitable for use with a wavelength of 587.6 nm, making it a versatile option for a wide range of optical systems. The lens is currently in stock, according to the vendor's website, ensuring quick and reliable delivery for your optical project needs.
