65-489 6.0mm Dia. x 6.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 65-489 is a 6.0mm diameter, plano-convex spherical lens, designed for use with a 633nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens features a 6.0mm focal length (FL), making it suitable for applications that require a tight focus. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light gathering and focusing. The lens has a center thickness of 2.5mm and an edge thickness of 1.42mm, providing a robust structure while maintaining a compact form factor.
The lens is made from n-SF11 Schott glass, a material known for its excellent optical properties and durability. This glass has a high refractive index and low dispersion, making it ideal for high-precision optical systems.
The lens is coated with Edmund Optics' Las V-Coat 633, a specialized coating designed for use with 633nm lasers. This coating enhances the lens's performance by reducing surface reflections and improving transmission, resulting in increased light efficiency and improved system performance.
