G312321331 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm
The G312321331 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is designed for use in optical systems that require a convex lens with a flat surface on one side. The lens is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens has an effective focal length (EFL) of 50mm, which is the distance from the lens's center to the focal point when the lens is used in air. This makes it suitable for applications that require a moderate level of magnification. The lens's geometry includes a thickness of 1.8mm at the edge and 5mm at the center, providing a robust structure while maintaining a low profile.
The G312321331 lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission, enhancing the performance of the lens in its intended application. The coating is designed for a wavelength of 588nm, which is within the visible light spectrum.
