The KPC019AR.18 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a 12.7 mm diameter and a focal length of -75 mm, making it ideal for applications that require a negative focal length. The lens's base shape is circular, and it features an inner radius of 0 mm and an outer radius of 0 mm.
The KPC019AR.18 is constructed from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens's geometry includes a thickness edge of 2.92 mm and a thickness center of 2.5 mm. The back focal length (bfl) is -76.64 mm, and the effective focal length (efl) is -75 mm.
This lens is coated with new ar-18 fromfigure on both the front and back, providing superior anti-reflective properties in the 1000-1550nm wavelength range. This coating enhances the lens's performance in infrared applications. The KPC019AR.18 is currently in stock and available for immediate purchase from the MKS/Newport website.
