89-003 5.0mm Dia. x 30.0mm FL; Plano-Convex Lens Laser V-Coat 633nm
The 89-003 is a high-quality Plano-Convex spherical lens, measuring 5.0mm in diameter and boasting a focal length of 30.0mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is designed for use with a wavelength of 633nm.
The lens is fabricated from the highly respected N-BK7 glass from Schott, ensuring excellent optical performance. The base shape of the lens is circular, and it features a plano-convex geometry, with the convex surface facing outwards. The edge thickness of the lens is 1.4mm, while the center thickness is slightly greater at 1.6mm.
The lens's effective focal length (EFL) is 30.0mm, and the radius of curvature (R1) of the curved surface is 15.5mm. The back focal length (BFL) of the lens is 28.95mm, and it has no inner or outer radius, indicating a uniform curvature.
The lens is coated with Edmund Optics' proprietary Las V-Coat 633, which is specifically designed for laser applications at a wavelength of 633nm. This coating ensures high transmission and low reflection, making it ideal for use in laser systems.
