KPC031 25.4 mm Dia. x -150 mm FL; Uncoated; Plano-Concave Lens
The KPC031 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of -150 mm, making it ideal for applications that require a negative focal length.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low optical dispersion, and high transparency in the visible and near-infrared spectral range. The base shape of the lens is circular, and it features an uncoated surface, providing a cost-effective solution for applications where coating is not a necessity.
The geometry of the lens is well-defined, with a thickness at the edge of 3.35 mm and a center thickness of 2.5 mm. The inner and outer radii are both 0, indicating a plano surface on both sides of the lens. The back focal length of the lens is -151.64 mm, slightly longer than its focal length due to the thickness of the lens.
This lens is designed to work with a wavelength of 589 nm, making it suitable for applications in the yellow-orange part of the visible light spectrum. Its uncoated surface ensures high transmittance in this region, making it an excellent choice for applications that require high light transmission.
