LA4158-633 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=250mm 633nm V-Coat
The LA4158-633 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use with a wavelength of 587.6 nm and boasts an effective focal length (EFL) of 250 mm, making it suitable for a wide range of optical applications.
The lens features a Plano-Convex geometry, with a thickness of 2 mm at the edge and 2.7 mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a sharply curved lens surface. This curvature, combined with the lens's material and coating, contributes to its high-performance optical characteristics.
The LA4158-633 is made from UVFS, a material with the ID 1965. This material, in combination with the lens's geometry and coating, ensures excellent optical transmission and minimal distortion. The lens is coated with a V-AR-633 coating on both the front and back surfaces, which further enhances its performance by reducing reflectance and increasing transmission at the specified wavelength.
