88-970 20.0mm Dia. x 20.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
The 88-970 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved outwards. This lens, sourced from Edmund Optics, boasts a diameter of 20.0mm and a focal length of 20.0mm, making it a compact and efficient optical component.
The lens is constructed from n-SF11 Schott, a high-index glass with excellent optical properties. This material is known for its low auto-fluorescence, making it ideal for laser applications. The lens has a center thickness of 4.6mm and an edge thickness of 1.0mm, providing robustness and durability.
The 88-970 features a V-coat designed for 405nm, enhancing its performance in laser applications. This coating, applied to both the front and back surfaces, ensures high transmission and low reflection at the specified wavelength. The lens's inner and outer radii are 0mm, indicating a uniform curvature.
The lens's effective focal length (EFL) is 20.0mm, and its back focal length (BFL) is 17.42mm. These parameters are crucial in determining the lens's placement and orientation in an optical system.
