G063022331 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=30mm

This is a G063022331 model lens, a high-quality optical component manufactured by Qioptiq Photonics. The lens has a base shape of a circle and features a double-convex geometry, making it suitable for a wide range of optical applications.

The lens has a diameter of 22.4 mm and a thickness that varies from 2 mm at the edge to 6.3 mm at the center. 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 type of glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum.

The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, which is particularly beneficial in applications where high light throughput is required.

The item data also indicates a wavelength of 587.6 nm, which is in the green part of the visible spectrum. This suggests that the lens is designed to work optimally in this wavelength range, although its performance may extend to other wavelengths as well.
