38-318 25.4mm Dia. x 40.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 38-318 is a Plano-Convex Spherical Lens, sourced from the renowned optical component vendor, Edmund Optics. This lens boasts a diameter of 25.4mm and a focal length of 40.0mm, making it suitable for a wide range of optical applications.
The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. This material ensures high transmission in the visible spectrum, making the lens ideal for applications within the wavelength range of 425-675nm.
The 38-318 features a standard coating on both the front and back surfaces. The coating, labeled as 'edm vis-0 std curve', is designed to enhance the lens's performance in the visible spectrum. This coating aids in reducing surface reflections, thereby increasing the overall transmission of the lens.
The geometry of the lens is well-defined, with a thickness of 1.54mm at the edge and 5.9mm at the center. The lens's inner and outer radii are both zero, indicating a uniform curvature across the surface. The base shape is circular, adding to the lens's versatility in various optical systems.
