LA1484 N-BK7 Plano-Convex Lens; Dia:1 in; f=300.0 mm Uncoated

The LA1484 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 1 inch, is designed for use in a variety of applications that require precise focusing or collimation of light.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a low coefficient of thermal expansion, making it resistant to thermal shock and suitable for use in a wide range of temperatures. The lens also features a plano-convex geometry, with a flat (plano) surface on one side and a curved (convex) surface on the other. This design allows for efficient light collection and focusing.

The geometry of the lens includes a diameter of 25.4 millimeters, a thickness at the edge of 2 millimeters, and a thickness at the center of 2.5 millimeters. The effective focal length (EFL) of the lens is 300 millimeters, which is the distance from the lens at which an object will be in focus. The radius of curvature of the curved surface is 154.5 millimeters, and the back focal length (BFL) is 297.3 millimeters.

Notably, this lens is uncoated. While coatings can be applied to reduce reflection and improve transmission, this lens is designed to operate without them. This can be advantageous in certain applications where the uncoated surface may be beneficial.
