The 112-0250E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -650 mm, sourced from EKSMA Optics. This lens is a spherical type, designed with a base shape of a circle, and is uncoated.
The lens's geometry includes a thickness edge of 3.9 mm and a thickness center of 3.7 mm. The effective focal length (EFL) is -650 mm, and the first radius of curvature (R1) is -337.2 mm. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other.
The lens is made of n-BK7 Schott material, a common type of optical glass known for its excellent optical properties. The wavelength for this lens is 546 nm.
Please note that this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may affect the lens's performance in certain applications, so it's essential to consider this when selecting components for your optical system.
