45-888 25mm Dia. x 35mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-888 is a high-quality double-convex lens, sourced from the renowned optical component vendor, Edmund Optics. This lens boasts a 25mm diameter and a focal length of 35mm, making it suitable for a wide range of applications.
The lens is crafted from the highly respected N-BK7 Schott glass, a material known for its excellent optical properties and versatility. This, coupled with its double-convex shape, allows for superior light transmission and focus, enhancing the overall performance of your optical system.
The 45-888 features a VIS-NIR coating on both the front and back surfaces. This coating, with a center wavelength of 587.6nm, is designed to optimize performance in the visible to near-infrared spectrum (400-1000nm). It significantly reduces surface reflections, thereby increasing transmission and improving image quality.
The lens has a thickness of 2mm at the edge and 6.6mm at the center, while the back focal length is 32.81mm. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
