G312358525 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=500mm 725-1050nm
The G312358525 is a Plano-Convex lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. This lens is designed for use in the 725-1050nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum.
The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, provides a focal length (EFL) of 500mm. This geometry is often used in imaging systems due to its ability to focus light efficiently.
The lens has a thickness of 2.9mm at the edge and 3mm at the center. The curvature of the lens is defined by a radius (R1) of 260.39mm on the curved side. The inner and outer radii are 0mm, indicating a uniform curvature.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the near-infrared range, reducing reflections and increasing transmission.
