KPC019 12.7 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens
The KPC019 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. This lens has a diameter of 12.7 mm and a base shape of a circle. The lens is uncoated, which means it does not have any additional layers to enhance or alter its optical properties.
The lens's geometry is characterized by its thickness at the edge, which is 2.92 mm, and its thickness at the center, which is 2.5 mm. The effective focal length (EFL) of this lens is -75 mm, indicating that it is a diverging lens, causing parallel rays to spread out.
The lens's first radius of curvature (R1) is -38.76 mm, and its back focal length (BFL) is -76.64 mm. The lens does not have an inner or outer radius, suggesting that it is a simple plano-concave lens without any additional curvature or features.
The lens is made of N-BK7 Schott, a common type of glass used in optical applications due to its excellent optical properties. The wavelength for this lens is 589 nm. This lens is in stock and available for immediate purchase, as indicated by its valid web link status.
