KBX139AR.33 50.8 mm Dia. x 38.1 mm FL; Double-Convex Lens Laser V-Coat 1064nm
This KBX139AR.33 double-convex lens, sourced from MKS/Newport, is a high-quality optical component designed for use in laser systems operating at a wavelength of 1064nm. The lens features a diameter of 50.8mm and a focal length of 38.1mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott glass, a popular material due to its excellent optical properties and broad transmission range. The double-convex geometry, with radii of curvature of 34.442mm for both the front and back surfaces, provides a high level of focusing power. The lens has a central thickness of 25.36mm and edge thickness of 3mm, contributing to its robustness and durability.
The lens is coated with New AR-33 fromfigure on both the front and back surfaces. This anti-reflective coating is specifically designed for use with 1064nm lasers and provides excellent transmission characteristics while minimizing unwanted reflections. The coating ensures high-quality performance and longevity of the lens.
