LDX-25.4-91.6-C 25.4 mm Dia. N-BK7 Image Grade Convex-Convex Lens; EFL=88.9mm Uncoated

This is the LDX-25.4-91.6-C, a high-quality convex-convex lens from CVI Laser Optics. The lens, which is 25.4 mm in diameter, is made from N-BK7, a popular glass type known for its excellent optical properties. This particular lens is uncoated, which means it does not have any additional layers to enhance or alter its optical properties.

The lens has a double convex shape, meaning both sides are curved outwards. The first radius of curvature (R1) is 91.6 mm, while the second radius of curvature (R2) is -91.6 mm. This specific curvature gives the lens an effective focal length (EFL) of 88.9 mm. The lens has a thickness of 2 mm at the edge.

The LDX-25.4-91.6-C is designed for use in the visible light spectrum, specifically at a wavelength of 546.1 nm. It's important to note that the lens is not coated, which means it may not perform optimally in environments with high levels of light scattering or in applications where high reflectivity could be a problem.

This lens is part of CVI Laser Optics' spherical lens catalog, which includes a wide range of lenses with various shapes, sizes, and materials. The catalog is available for download on the CVI Laser Optics website. According to the vendor, this lens is currently in stock.
