G311329322 8 mm Dia. N-BAK4 Double-Convex Lens; EFL=7mm 450-700nm
The G311329322 is a high-quality spherical lens from Qioptiq Photonics, designed for precision optics applications. This lens, with a diameter of 8 mm, is a symmetric convex-convex lens, also known as a double-convex lens, which means it has two convex surfaces.
The lens has a center thickness of 3.4 mm and an edge thickness of 1.1 mm, providing a robust structure for various applications. The effective focal length (EFL) of this lens is 7 mm, making it suitable for systems that require a compact lens with a short focal length.
The lens is made from N-BAK4 Schott glass, a high-index, low-dispersion material that is often used in optical systems that require high performance and excellent image quality. The N-BAK4 glass also has a high Abbe number, which reduces chromatic aberration, ensuring clear and sharp images across the visible spectrum.
The G311329322 lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2visnbk7, is designed to reduce surface reflections and increase transmission in the 450-700 nm spectral range. This makes the lens ideal for use in systems that require high transmission and low reflectance, such as imaging systems, beam delivery systems, and optical metrology instruments.
