KPX202 50.8 mm Dia. x 250 mm FL; Uncoated; Plano-Convex Lens
The KPX202 is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a circular base shape with a diameter of 50.8 mm and a thickness at the edge of 3 mm. The center thickness is 5.521 mm, and it has an effective focal length (EFL) of 250 mm. The lens's radius of curvature (RoC) is 129.2 mm, and the back focal length (BFL) is 246.36 mm.
The KPX202 is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This lens is designed to operate at a wavelength of 589 nm. Notably, this lens does not have any coating, which means it is uncoated. While uncoated lenses can be more cost-effective, they may have lower transmission rates and are more susceptible to surface damage compared to coated lenses.
