G312326322 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm 450-700nm
The G312326322 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is designed for use in the visible spectrum, specifically optimized for wavelengths between 450nm and 700nm. The Plano-Convex design, where one side is flat and the other is curved, is a common choice for applications that require a simple, single-element lens.
The lens has an effective focal length (EFL) of 300mm, which is a measure of the lens's optical power. This makes it suitable for use in systems that require moderate to high magnification. The lens is made from N-BK7, a type of glass known for its excellent optical properties, including high transmission in the visible spectrum and low dispersion.
The lens's geometry includes a thickness of 3.5mm at the edge and 4mm at the center. The radius of curvature (R1) is 153.99mm. The lens is unmounted, meaning it does not come with any housing or mounting hardware.
The lens features broadband anti-reflection coatings on both the front and back surfaces. These coatings are designed to reduce surface reflections, improving the lens's light transmission and reducing unwanted ghosting and flaring effects. The coating type is qio bbar arb2visnbk7.
