G311310525 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm 725-1050nm
This is a G311310525 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 center thickness of 6.3 mm and an edge thickness of 2 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 30 mm, which is a common choice for many optical systems due to its versatility.
The lens is made of N-BK7, a popular material in the optical industry, known for its excellent optical properties. This material is identified by its refractive index and Abbe number, which are crucial in determining the lens's performance in different wavelengths.
The G311310525 lens is coated with qio bbar arb2nirnbk7 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.
The lens is designed to operate within the wavelength range of 725-1050 nm, making it suitable for near-infrared (NIR) applications. The lens's geometry, including its curvature radii (r1 and r2), is optimized for this wavelength range, ensuring optimal performance.
