LA1384 N-BK7 Plano-Convex Lens; Dia:2 in; f=125.0 mm Uncoated

The LA1384 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 2 inches, is designed to focus or collimate light beams in various applications.

The lens is made of N-BK7, a borosilicate glass commonly used in optical systems due to its excellent optical properties. It has a planoconvex geometry, meaning one side is flat, and the other is curved, focusing light to a point. The radius of curvature of the curved surface is 64.4 mm, and the lens has a focal length of 125 mm, making it suitable for applications requiring a longer focal length.

The lens's clear aperture is 50.8 mm, and it has a thickness of 3 mm at the edge and 8.2 mm at the center. The back focal length, the distance from the lens's rear surface to the focal point, is 119.2 mm. The lens is uncoated, meaning it does not have any anti-reflective coatings. However, it can be customized with various coatings upon request.

This lens is designed to work with a wavelength of 587.6 nm, making it suitable for applications in the visible spectrum. It is a spherical lens, meaning it has a spherical surface, which is the simplest and most common type of lens surface.
