This is a 12mm diameter, 45mm focal length double-convex lens, sourced from the reputable optical components vendor, Edmund Optics. The lens is designed for use within the visible light spectrum, specifically optimized for a wavelength of 587.6nm.
The lens features a standard anti-reflective coating on both the front and back surfaces, which is identified as 'edm vis-0 std curve'. This coating is designed to minimize surface reflections and increase transmission, thereby enhancing the overall performance of the lens in its intended application.
The lens geometry is characterized by its spherical shape, with a first radius of curvature (R1) of 40.79mm and a second radius (R2) of -40.79mm. The lens has an edge thickness of 2.1mm and a center thickness of 2.99mm. The back focal length (BFL) is 43.96mm, and the effective focal length (EFL) is 45mm.
The lens is made from fused silica, identified as 'fused sil mal-1965' in the material data. This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens is designed for use within the UV spectrum, specifically within the range of 425-675nm. This makes it suitable for use in a variety of applications, including UV imaging and spectroscopy.
