G312333331 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=100mm
The G312333331 is a 31.5 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a leading provider of precision optics. This lens, designed for use in various optical systems, boasts an effective focal length (EFL) of 100mm, making it suitable for applications requiring moderate magnification.
The lens is made from N-BK7, a popular optical glass due to its excellent optical properties and high Abbe number. The Plano-Convex geometry, with a curvature radius of 52.33mm on the convex side, ensures light is efficiently focused or collimated. The lens has a thickness of 2.1mm at the edge and 4.5mm at the center, providing robustness and structural integrity.
The lens features a broadband anti-reflection coating, Qio AL RALVIS AOI 45, on both the front and back surfaces. This coating reduces surface reflections, enhancing transmission and improving overall system performance. The coating is designed for a central wavelength of 588nm, making it suitable for applications in the visible spectrum.
