G311346000 40 mm Dia. N-BK7 Double-Convex Lens; EFL=200mm 450-700nm
Discover the G311346000, a 40 mm diameter N-BK7 double-convex lens, from the esteemed optical components manufacturer, Qioptiq Photonics. This lens, designed for use in the visible light spectrum (450-700nm), boasts an effective focal length (EFL) of 200mm, making it an ideal choice for a wide range of optical applications.
The lens is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and a high refractive index. This material ensures superior image quality and durability, making it a popular choice in various optical systems.
The G311346000 features a double-convex geometry, with a 2.1mm edge thickness and a 4mm center thickness. This design allows for efficient light transmission and focusing, enhancing the overall performance of your optical system. The lens's inner and outer radii are 0, indicating a symmetrical convex-convex shape.
The lens is coated with Qioptiq's proprietary qio bbar arb2visnbk7 coating on both the front and back surfaces. This coating is specifically designed to reduce reflection and increase transmission in the visible light spectrum, further optimizing the lens's performance.
