48-936 9mm Dia. x -12mm FL; MgF2 Coated; Double-Concave Lens 400-700nm
The 48-936 is a double-concave lens with a 9mm diameter and a focal length of -12mm, making it a negatively powered lens. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components. The lens is made from n-SF11 Schott, a glass material with excellent optical properties, particularly in the visible spectrum.
The lens features a MgF2 coating on both the front and back surfaces. This coating, standard from Edmund Optics, is designed to reduce reflection and increase transmission across the 400-700nm wavelength range. The coating is applied using a standard curve, ensuring consistent performance and reliability.
The lens has a center thickness of 1.5mm and an edge thickness of 2.43mm, providing a robust and durable structure. The inner and outer radii are not specified, indicating that they are not a significant factor in the lens's performance or application.
