38-313 18.0mm Dia. x 20.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 38-313, is characterized by its 18.0mm diameter and 20.0mm focal length, making it a versatile choice for various optical applications.
The lens is constructed from n-sf11 Schott, a high-index glass material known for its excellent optical properties. This material, combined with the lens's plano-convex geometry, facilitates efficient light transmission and focusing. The lens's geometry includes a 1.46mm edge thickness and a 4.3mm center thickness, contributing to its robustness and durability.
The 38-313 lens features a VIS 0° coating on both its front and back surfaces. This anti-reflective coating is designed to minimize surface reflections within the visible spectrum (425-675nm), thereby enhancing the lens's overall light transmission efficiency. The coating also helps to reduce ghosting and flare, thereby improving the quality of the optical system in which the lens is used.
