G312318322 22.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=100mm 450-700nm

This is a G312318322 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 3.2 mm, making it suitable for a wide range of optical applications. The lens is made of N-BK7, a popular optical glass known for its excellent optical properties and high damage threshold.

The lens has an effective focal length (EFL) of 100 mm, which is the distance from the lens's center to the focal point when the lens is used in air. This makes it a medium to long-focus lens, ideal for applications that require a narrow beam or high magnification. The lens is designed to work in the wavelength range of 450-700 nm, which covers the visible light spectrum.

The lens features a Qio Bbar ARB2VISNBK7 coating on both the front and back surfaces. This anti-reflection coating reduces surface reflections and increases transmission, enhancing the lens's performance in high-light applications. The lens has a spherical shape, which is the simplest and most common type of lens shape.

The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows users to customize the lens to their specific needs and applications. The lens is currently in stock and available for purchase on the Qioptiq Photonics website.
