69-437 12.0mm Dia. x 15.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 69-437 is a Plano-Convex Spherical Lens, 12.0mm in diameter and featuring a 15.0mm focal length. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry, and is designed for use with a 633nm wavelength, making it suitable for a variety of applications in the visible light spectrum.
The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for use in laser applications due to its high damage threshold. The lens features a Plano-Convex geometry, with a 7.75mm radius of curvature on the convex side and a 0mm radius on the planar side. This geometry provides a large clear aperture and excellent optical performance.
The lens is coated with Edmund Optics' Las V-Coat 633, a broadband anti-reflection coating designed for use with the 633nm wavelength. This coating reduces surface reflections to less than 0.5%, enhancing the lens's transmission and overall performance. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
