KBC022AR.33 12.7 mm Dia. x -50 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The KBC022AR.33 is a high-quality spherical lens, specifically designed for use in laser systems operating at a wavelength of 1064nm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliability and performance.
The lens is designed with a concave-concave base shape, featuring a diameter of 12.7mm and a thickness of 3.13mm at the edge, tapering to 2.5mm at the center. The effective focal length (EFL) is -50mm, making it suitable for use in systems requiring a negative focal length. The back focal length (BFL) is -50.81mm, and the radii of curvature for the front and back surfaces are -52.103mm and 52.103mm respectively.
The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission in the visible and near-infrared regions. This material is well-suited for use in laser systems.
The KBC022AR.33 features a double-sided anti-reflective coating, specifically the New AR-33 from Figure, which provides excellent transmission and reduces unwanted reflections. This coating is designed for use at a wavelength of 1064nm, ensuring optimal performance in your laser system.
