48-536 25mm Dia. UVFS Aspheric Lens; EFL=25mm; NA=0.5 Uncoated

The 48-536 is a 25mm Dia. UVFS (Ultra-Violet Fused Silica) Aspheric Lens, featuring a high numerical aperture (NA) of 0.5 and an effective focal length (EFL) of 25mm. This lens is uncoated, offering a cost-effective solution for applications where coating is not required.

The lens is manufactured from syn hpfs7980 Corning, a high-performance fused silica material renowned for its excellent transmission properties across a wide spectral range, including the ultraviolet region. This makes the 48-536 particularly suitable for UV applications.

The aspheric design of the lens helps to minimize spherical aberration, a common optical issue that can degrade image quality. This is achieved through the precise shaping of the lens surface, which deviates from the standard spherical shape. The lens features a first radius of curvature (r1) of 11.462 and a second radius of curvature (r2) of 0, demonstrating its unique aspheric profile.

The lens has a diameter of 25mm and a thickness at the edge of 1.75mm. The thickness at the center is 9.75mm. The front surface of the lens has a conic constant of -1.6612216, with higher-order aspheric terms of 0, 3.5564738e-10, -1.0410485e-13, and 0 for the coefficients e, f, g, and h, respectively.
