LC1315 N-BK7 Plano-Concave Lens; Dia:2 in; f=-75.0 mm Uncoated

The LC1315 N-BK7 Plano-Concave 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 2 inches, is designed for use in a variety of optical systems, offering a focal length of -75.0 mm, making it suitable for applications that require a concave lens.

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 optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens's geometry includes a planar surface and a concave surface with a radius of curvature of -38.6 mm. The lens's thickness varies from 3.5 mm at the center to 13 mm at the edge.

The lens is uncoated, meaning it does not have any additional layers applied to its surfaces to alter its optical properties. This can be beneficial in applications where the user desires to apply their own coatings or where the uncoated surface is suitable for the application's requirements.
