G311317322 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=80mm 450-700nm
This is a G311317322 double-convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens has a base shape of a circle and a diameter of 22.4 mm, making it suitable for a wide range of optical applications.
The lens features a thickness of 2 mm at the edge and 3.5 mm at the center, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is 80 mm, which is a common choice for many optical systems due to its versatility.
The lens is made of N-BK7, a high-quality glass material known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum, specifically 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 performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
In terms of geometry, the lens has a first radius (r1) of 83.536 mm and a second radius (r2) of -83.536 mm. The inner and outer radii are both 0 mm, indicating a symmetrical lens design.
