G312358400 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=500mm

The G312358400 is a 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, a leading provider of precision optics. This lens boasts an effective focal length (EFL) of 500mm, making it suitable for a wide range of applications that require long focal lengths.

The lens is made of N-BK7, a popular optical glass known for its excellent optical properties, including high transparency across the visible spectrum and low dispersion. This material is particularly suitable for applications that require high image quality and color correction.

The G312358400 features a spherical geometry, with a convex surface radius of 260.39mm. The lens has a thickness of 2.9mm at the edge and 3mm at the center, providing a robust structure while maintaining a low profile. The lens is unmounted, allowing for easy integration into various optical systems.

The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.

The lens is currently in stock and available for purchase through the Qioptiq Photonics website. With its high-quality materials, precise geometry, and advanced coating, the G312358400 is an excellent choice for applications that require a long focal length lens with superior optical performance.
