G311328322 6 mm Dia. N-BAK4 Double-Convex Lens; EFL=5mm 450-700nm
The G311328322 is a high-quality spherical lens from Qioptiq Photonics, designed for use in the visible light spectrum, specifically between 450 and 700nm. This lens, with a base shape of a circle, is a symmetric convex-convex lens, making it ideal for a wide range of optical applications.
The lens has a diameter of 6mm and a center thickness of 2.9mm, ensuring a robust and durable construction. The edge thickness is 0.9mm, providing a balanced profile that minimizes optical distortion. The effective focal length (EFL) of this lens is 5mm, making it suitable for use in systems where a compact, high-performance lens is required.
The lens is made from n-Bak4 Schott, a high-index material known for its excellent optical properties. This material ensures high transmittance and low dispersion, making it ideal for applications where image quality is paramount.
The G311328322 lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2visnbk7, reduces surface reflections and increases transmission, further enhancing the lens's performance.
