LA1353 N-BK7 Plano-Convex Lens; Dia:75.0 mm; f=200.0 mm Uncoated

The LA1353 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 75.0 mm, is designed for use in a wide range of optical systems, offering a focal length of 200.0 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 lens includes a thickness of 3 mm at the edge and 10.1 mm at the center. The effective focal length (EFL) is 200.0 mm, and the radius of curvature (R1) is 103 mm. The back focal length (BFL) is 192.7 mm, and the lens has no inner or outer radius, indicating a uniform thickness across the lens.

This particular lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in reducing reflection, increasing transmission, or protecting the lens surface, an uncoated lens can be suitable for applications where such enhancements are not required.
