89-142 10mm Dia. x 10mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
The 89-142 is a double-convex lens with a diameter of 10mm and a focal length of 10mm, making it a versatile choice for various optical applications. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The lens is made from n-SF5 Schott, a material with excellent optical properties. It is designed to operate at a wavelength of 587.6nm, which is within the visible light spectrum. This makes it suitable for applications that require the transmission of visible light, such as imaging systems or light guides.
The lens features VIS-EXT coatings on both the front and back surfaces. These coatings are specifically designed to enhance the transmission of visible light, further improving the lens's performance in its intended application range of 350-700nm. The edge thickness of the lens is 1.45mm, while the center thickness is 3.5mm, providing a robust and durable structure.
The base shape of the lens is circular, and its geometry is spherical, with radii of curvature of 12.71mm and -12.71mm for the first and second surfaces, respectively. The back focal length of the lens is 8.89mm, and it has no inner or outer radius, indicating a uniform curvature across the lens surface.
