G311338322 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=20mm 450-700nm
This is a G311338322 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is a symmetric convex-convex type, featuring a base shape of a circle, which is typical for such optical elements.
The lens has a diameter of 22.4 mm, making it suitable for a wide range of applications that require a substantial light-gathering area. The edge thickness is 1.6 mm, while the center thickness is 8.8 mm, providing a robust structure and ensuring minimal distortion.
The effective focal length (EFL) of this lens is 20 mm, which is a common choice for many optical systems due to its versatility. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, specifically between 450 and 700 nm, making it ideal for applications such as imaging, metrology, and beam shaping.
