KPC043 25.4 mm Dia. x -25 mm FL; Uncoated; Plano-Concave Lens
The KPC043 is a plano-concave lens with a diameter of 25.4 mm and a focal length of -25 mm, making it a negatively powered lens. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to enhance or alter its optical properties.
The lens is made of N-BK7 Schott, a popular material for optical lenses due to its excellent optical properties and wide transmission range. The lens's geometry includes a thickness of 9.4 mm at the edge and 2.5 mm at the center, with an effective focal length (EFL) of -25 mm. The radius of curvature for the first surface (R1) is -12.92 mm, and the back focal length (BFL) is -26.64 mm.
This lens is designed for use in the visible spectrum, specifically at a wavelength of 589 nm. Its spherical shape ensures consistent optical performance across the entire surface of the lens. The lens's base shape is circular, which adds to its versatility in various optical applications.
