38-281 12.0mm Dia. x 25mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-281 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.0mm diameter and a 25mm focal length (FL), making it suitable for a wide range of optical applications. The lens is fabricated from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The curvature of the lens is defined by a radius of 12.92mm, and the lens has a central thickness of 2.7mm and an edge thickness of 1.22mm. The effective focal length (EFL) is 25mm, and the back focal length (BFL) is 32.22mm.
The 38-281 lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically within the 425-675nm range. The lens's coating ensures high transmission, low reflectance, and improved durability, making it an excellent choice for various optical systems.
