The LA1172 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 a focal length of 400.0 mm.
The lens is made of 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 lens's geometry is plano-convex, meaning it has a flat surface and a curved surface. This design is often used to focus light, making it ideal for imaging and beam shaping applications.
The lens's geometry includes a diameter of 25.4 mm, with a thickness of 2 mm at the edge and 2.4 mm at the center. The effective focal length (EFL) is 400.0 mm, and the radius of curvature (R1) is 206 mm. The back focal length (BFL) is 397.1 mm, and both the inner and outer radii are 0 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can be beneficial in certain applications, an uncoated lens can be a cost-effective solution when such enhancements are not necessary.
