LB1409 N-BK7 Bi-Convex Lens; Dia:1 in; f=1000.0 mm Uncoated

The LB1409 N-BK7 Bi-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 at a focal length of 1000.0 mm, making it suitable for a wide range of applications that require long-distance focusing.

The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it ideal for use in high-precision optical systems. The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties.

The geometry of the lens is defined by its diameter, thickness, and radii of curvature. The lens has a diameter of 25.4 mm, with a thickness of 2 mm at the edge and 2.2 mm at the center. The radii of curvature are 1029.8 mm for the first surface and -1029.8 mm for the second surface, indicating a bi-convex design. The back focal length of the lens is 999.3 mm, and the effective focal length is 1000.0 mm.

This lens is a versatile and reliable choice for a variety of optical applications. Its high-quality materials and precise construction ensure excellent performance and durability. Whether you're working on a research project, designing a custom optical system, or simply need a high-quality lens for general use, the LB1409 N-BK7 Bi-Convex Lens is an excellent choice.
