G063014322 31.5 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=70mm 450-700nm
This is a mounted double-convex lens with a diameter of 31.5 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards, which is ideal for applications requiring a strong converging lens.
The lens has an effective focal length (EFL) of 70 mm, making it suitable for medium to long-range focusing applications. The edge thickness of the lens is 2.1 mm, while the center thickness is 5.5 mm, providing a good balance between weight and optical performance. The lens's inner and outer radii are 0, indicating a symmetrical design, which can help minimize optical aberrations.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible light spectrum, specifically between 450 and 700 nm. The coating reduces reflection and increases transmission, improving the lens's overall efficiency and image quality.
