69-585 50.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 980nm
This is a 69-585 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 50.0mm and a focal length of 250.0mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. The base shape of the lens is circular, and it features a spherical geometry. The edge thickness of the lens is 2.5mm, while the center thickness is 246.74mm. The effective focal length (EFL) of the lens is 250mm, and the back focal length (BFL) is also 246.74mm.
The lens is coated with Edmund Optics' Laser V-Coat 980, a broadband anti-reflection coating designed for use in the near-infrared region. This coating provides high transmission and low reflectance across the 980nm wavelength, making the lens ideal for laser applications.
The lens is currently in stock and available for immediate shipping. For more information, please refer to the vendor's website or contact their sales team.
