KBX175AR.18 50.8 mm Dia. x 400 mm FL; IR coated; Double-Convex Lens for IR 1000-1550nm
This is a high-quality Double-Convex Lens, specifically designed for use in the infrared spectrum, with a wavelength of 589nm. The lens, sourced from the reputable vendor MKS/Newport, is a Spherical Lens (Convex-Convex) type, featuring a circular base shape.
The lens has a diameter of 50.8mm and a thickness at the edge of 3mm, while the center thickness measures 4.565mm. The Effective Focal Length (EFL) is 400mm, and the first and second radii of curvature are 412.674mm and -412.674mm respectively. The Back Focal Length (BFL) is 398.49mm, and both the inner and outer radii are 0mm.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties. The lens features New AR-18 coating on both the front and back surfaces, designed to reduce reflection and increase transmission in the infrared spectrum, specifically for the 1000-1550nm range.
