38-476 25.4mm Dia. x 125.0mm FL; VIS-EXT Coated; Plano-Convex Lens VIS-EXT 350-700nm

The 38-476 is a Plano-Convex Spherical Lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a diameter of 25.4mm and a focal length of 125.0mm, making it a versatile choice for various 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 it ideal for applications that require clear, bright images.

The 38-476 lens features a VIS-EXT coating on both the front and back surfaces. This coating, specifically designed for the visible spectrum (350-700nm), enhances the lens's overall light transmission and reduces surface reflections. The result is improved image quality and increased system efficiency.

The lens's geometry is another notable feature. It has a thickness of 1.74mm at the edge and 3mm at the center, providing a robust structure while maintaining a sleek profile. The inner and outer radii are 0mm, indicating a uniform curvature throughout the lens.
