112-0215E 25.4 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens
The 112-0215E is a plano-concave lens with a diameter of 25.4 mm and a focal length of -75 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 an edge thickness of 4.9 mm and a center thickness of 2.9 mm. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens. The effective focal length (EFL) is -75 mm, suggesting a strong converging effect, which is typical of plano-concave lenses.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The wavelength for this lens is 546 nm, which falls within the visible light spectrum.
This lens is a versatile optical component, suitable for various applications where a strong converging effect is required. It is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the weblinks section.
