The KPX217-C is a Plano-Convex lens, a type of spherical lens, sourced from the renowned optical components manufacturer, MKS/Newport. This lens, with a base shape of a circle, has a diameter of 50.8 mm and a thickness at the edge of 3 mm, transitioning to a center thickness of 3.625 mm. The effective focal length (EFL) of this lens is 1000 mm, making it suitable for applications requiring long focal lengths.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with MgF2, a material known for its high refractive index and low dispersion, which enhances the lens's performance in the spectral range of 400-700 nm.
