G312312331 40 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm
The G312312331 is a 40 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a leading provider of precision optics. This lens is designed for use in a wide range of optical systems, offering a focal length of 50mm (EFL).
The lens is made from N-BK7, a high-quality borosilicate glass, known for its excellent optical properties and durability. The Plano-Convex geometry, with a spherical shape, features a flat (plano) surface on one side and a curved (convex) surface on the other. This design allows for efficient light collection and focusing, making it suitable for various applications.
The lens has a center thickness of 11.8mm and an edge thickness of 2.6mm, providing a robust structure while maintaining a low profile. The front and back surfaces of the lens are coated with Qio AL RALVIS AOI 45, a broadband anti-reflection coating, which enhances transmission and reduces surface reflections.
The item data also indicates a wavelength of 588nm, suggesting that this lens is optimized for use in the yellow-orange part of the spectrum. However, due to the broadband nature of the anti-reflection coating, it can be used across a wider range of wavelengths.
