38-601 18.0mm Dia. x 25.0mm FL; YAG-BBAR Coated; Plano-Convex Lens YAG-BBAR 500-1100nm
The 38-601 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm and a focal length of 25.0mm, is designed for use within the wavelength range of 500-1100nm, making it suitable for a wide range 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 enhances transmission and reduces surface reflections. This coating is specifically designed for use within the 500-1100nm wavelength range, further enhancing the lens's performance within this spectrum.
The lens's geometry includes a thickness at the edge of 1.65mm and a thickness at the center of 5.3mm. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 21.51mm. The lens does not have an inner radius or an outer radius, indicating a simple, straightforward design.
