BICX-FS18 25.4 mm Dia. x 1000 mm FL; Uncoated; Double-Convex Lens

The BICX-FS18 is a high-precision, double-convex lens, characterized by its 25.4 mm diameter and 1000 mm focal length. This lens is sourced from WTS Photonics, a reputable vendor in the optical industry. The lens's base shape is circular, and it features a spherical geometry, making it suitable for a wide range of optical applications.

The lens's geometry includes a thickness of 2 mm at the edge and 2.18 mm at the center, with an effective focal length (EFL) of 1000 mm. The first and second radii of curvature (R1 and R2) are 919.8 mm and -919.8 mm, respectively, contributing to its double-convex design. The back focal length (BFL) is 999.24 mm, and both the inner and outer radii are 0 mm.

The lens is made from fused silica, specifically identified as mal-1965 in the Material ID. This material is known for its excellent optical properties, making it an ideal choice for applications that require high precision and clarity. The lens is uncoated, which may be suitable for certain applications, but users should consider the potential implications of this, such as increased susceptibility to environmental factors and reduced transmission in certain wavelength ranges.

The lens is designed to operate at a wavelength of 546.1 nm. This wavelength is within the visible light spectrum, making the lens suitable for applications that involve visible light.
