G312314322 22.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=40mm 450-700nm
The G312314322 is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. This lens, with a base shape of a circle, has a diameter of 22.4 mm and a thickness at the edge of 1.7 mm. The center thickness is 5 mm, and the effective focal length (EFL) is 40 mm, making it suitable for use in systems with a wavelength of 588 nm.
The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and versatility. The geometry of the lens includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the curved surface is defined by a radius of 20.83 mm.
The lens features broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as 'qio bbar arb2visnbk7', are designed to reduce reflection and increase transmission across the visible spectrum (450-700 nm). This makes the lens ideal for use in applications where high transmission and low loss are critical, such as imaging systems, beam shaping, and laser applications.
