G312356331 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm
The G312356331 is a 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a renowned provider of precision optics. This lens, designed for use in the visible light spectrum with a center wavelength of 588 nm, is made from N-BK7, a popular borosilicate glass known for its excellent optical properties.
The lens features a focal length (EFL) of 200mm, making it suitable for applications that require moderate magnification. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a thickness of 2.8mm at the edge and 3mm at the center, providing a robust structure while maintaining a low profile.
The G312356331 is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections, enhancing the transmission of light through the lens. The coating is designed for a 45-degree angle of incidence, ensuring optimal performance across a wide range of applications.
