SPX022AR.3 25.4 mm Dia. x 100 mm FL; AR coated; Plano-Convex Lens AR 355nm
The SPX022AR.3 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a diameter of 25.4 mm, is designed for use with a wavelength of 589 nm and features Anti-Reflective (AR) coatings on both the front and back surfaces.
The lens's geometry is characterized by a thickness of 3 mm at the edge and 4.792 mm at the center, with an effective focal length (EFL) of 100 mm. The front surface of the lens has a radius of curvature (R1) of 45.9 mm, resulting in a back focal length (BFL) of 96.71 mm. The lens is made from fused silica, specifically from the material ID mal-1965.
The AR coating on the lens is New AR-3 fromfigure, which is specifically designed to reduce surface reflections and increase transmission. This coating is particularly effective at the 355 nm wavelength, making this lens ideal for applications that require high transmission at this wavelength.
