G052202322 8 mm Dia. N-BAK4 Mounted Double-Convex Lens; EFL=7mm 450-700nm
This is the G052202322 model from Qioptiq Photonics, a high-quality mounted double-convex lens with a diameter of 8 mm. The lens is made from N-BAK4 Schott, a renowned optical material known for its excellent transmittance and homogeneity.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is often used to increase the optical power of a lens or to reduce spherical aberration. The lens's center thickness is 3.4 mm, while the edge thickness is 1.1 mm, providing a robust structure and ensuring minimal distortion.
The effective focal length (EFL) of this lens is 7 mm, which is the distance from the lens's secondary principal plane to the focal point when the lens is imaging an object at infinity. This EFL makes the lens suitable for various applications, including optical imaging systems, beam shaping, and laser applications within the wavelength range of 450-700 nm.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's durability and resistance to environmental factors, while also reducing reflection and improving transmission.
