The 111-1234E is a double-convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a base shape of a circle and is designed for use with a wavelength of 355 nanometers. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens has a diameter of 25.4 millimeters and a thickness at the edge of 2.4 millimeters. The center thickness is slightly greater at 3 millimeters. The effective focal length (EFL) of this lens is 300 millimeters. The first radius of curvature (R1) is 285.2 millimeters, while the second radius of curvature (R2) is -285.2 millimeters, indicating the lens's double-convex shape.
The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet spectrum. This makes the lens suitable for applications that require precise manipulation of ultraviolet light.
