This is a G063031322 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is spherical in shape, specifically a symmetric convex-convex lens, and is mounted on fused silica (UVFS). It has a base shape of a circle, with a diameter of 22.4 mm.
The lens has a thickness of 1.7 mm at the edge and 3.3 mm at the center. The effective focal length (EFL) of this lens is 80 mm, making it suitable for applications that require a longer focal length. The lens is designed to work within the wavelength range of 450-700 nm, which covers the visible light spectrum.
The lens features a coating on both the front and back surfaces. The coating is Qioptiq's BBAR ARB2VISNBK7, which is designed to reduce reflection and improve transmission in the visible light spectrum. This coating enhances the lens's performance in applications that require high transmittance and low reflectance.
