G312328331 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=1000mm

The G312328331 is a 25.4 mm diameter Plano-Convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. This lens is designed for use in a wide range of optical systems, thanks to its versatile specifications and high-quality construction.

The lens features a N-BK7 Schott material ID, a common choice in optical systems due to its excellent optical properties and high Abbe number. The N-BK7 Schott glass offers a high refractive index and low dispersion, making it suitable for various applications, including laser systems, beam shaping, and imaging systems.

The G312328331 lens has an effective focal length (EFL) of 1000mm, providing a long focal length that can be beneficial in applications requiring a narrow field of view or high magnification. The lens's geometry includes a 3.8mm thickness at the edge and a 4mm thickness at the center, contributing to its robust design and overall durability.

The lens's front and back surfaces are coated with Qio AL RALVIS AOI 45, a specialized anti-reflection coating that reduces surface reflections and increases transmission. This coating is designed for a central wavelength of 588nm, making it suitable for applications in the visible spectrum.
