67-278 50mm Dia. UVFS Aspheric Lens; EFL=60mm; NA=0.42 VIS 425-675nm

The 67-278 50mm Dia. UVFS Aspheric Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a catalog number of 67-278, is designed for use in the visible light spectrum, specifically between 425 and 675 nanometers.

The lens is made from UV Fused Silica, a material with the synonym hpfs7980 corning, known for its excellent transparency and durability. The lens features a circular base shape with a diameter of 50 millimeters, making it suitable for a wide range of optical applications.

The lens's geometry includes an inner radius of 0, an outer radius of 0, a thickness at the edge of 4.42 millimeters, and an effective focal length (EFL) of 60 millimeters. The lens's front surface has a radius of curvature (R1) of 27.508 millimeters and a thickness at the center of 17 millimeters. The lens's numerical aperture (NA) is 0.42, indicating a wide acceptance angle for light rays.

The lens's front and back surfaces are coated with edm vis 425-675nm, a coating specifically designed for use in the visible light spectrum. This coating enhances the lens's transmission and reduces reflection, thereby improving the overall performance of the optical system in which it is used.

The lens's shape is aspheric, which means it has a non-spherical surface. This design helps to reduce spherical aberration, a common optical distortion, and improves the lens's overall imaging performance.
