69-335 10.0mm Dia. x 75.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 69-335 is a high-quality Plano-Convex spherical lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 10.0mm diameter and a focal length of 75.0mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-grade material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transmission in the visible spectrum and excellent homogeneity. This material ensures the lens delivers sharp, clear images with minimal distortion.
The 69-335 features a Plano-Convex geometry, with a flat front surface and a curved back surface. The lens has a center thickness of 3.0mm and an edge thickness of 2.68mm, providing robustness and durability. The back focal length (BFL) is 73.02mm, and the effective focal length (EFL) is 75.0mm, indicating a moderate level of magnification.
The lens is coated with Edmund Optics' Laser V-Coat 405, a broadband anti-reflection coating designed for use with lasers at a wavelength of 405nm. This coating reduces surface reflections, enhancing the lens's transmission and improving overall system performance.
