38-604 25.4mm Dia. x 35.0mm FL; YAG-BBAR Coated; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-604 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 25.4mm and a thickness at the edge of 1.69mm, while the center thickness is 6.9mm. The effective focal length (EFL) of this lens is 35mm, making it suitable for a variety of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back surfaces of the lens are coated with YAG-BBAR, a type of anti-reflection coating that operates within the wavelength range of 500-1100nm. This coating reduces surface reflections, increasing the amount of light transmitted through the lens, thereby improving the overall efficiency and performance of the optical system.
The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) of the curved surface is 18.09mm, and the back focal length (BFL) is 30.46mm.
This lens is available from Edmund Optics and is currently in stock, making it an ideal choice for those in need of a high-quality, reliable optical component.
