89-002 5.0mm Dia. x 25.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 89-002 is a high-quality Plano-Convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 5.0mm and a focal length of 25.0mm, is designed for use with a wavelength of 633nm, making it ideal for a variety of applications in the visible spectrum.
The lens is constructed from Schott's n-BK7 glass, a material known for its excellent optical properties and wide transparency range. The base shape of the lens is circular, and it features a plano-convex geometry, with the convex surface facing outwards. The center thickness of the lens is 1.6mm, while the edge thickness is 1.36mm, providing a robust and durable structure.
The lens's surface has been treated with Edmund Optics' Laser V-Coat, a proprietary coating designed for use with 633nm lasers. This coating enhances the lens's performance by reducing surface reflections and improving transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
The lens's shape is spherical, with a radius of curvature of 12.92mm on the convex surface. The back focal length of the lens is 23.95mm, and the effective focal length is 25.0mm. The lens does not have any inner or outer radii, indicating a simple and straightforward design.
