112-0235E 25.4 mm Dia. x -250 mm FL; Uncoated; Plano-Concave Lens
The 112-0235E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -250 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 is meticulously crafted, with a thickness at the edge of 3.7 mm and a center thickness of 3.1 mm. The effective focal length (EFL) is -250 mm, and the first radius of curvature (R1) is -129.7 mm. The inner and outer radii are both zero, indicating a plano surface.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. 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 factor when selecting optical components.
