G314317525 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-150mm 725-1050nm

This is a Plano-Concave lens, type N-BK7, from the renowned optical components manufacturer, Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm. The effective focal length (EFL) of this lens is -150mm, making it a negative or diverging lens.

The lens is designed to operate within the wavelength range of 725-1050nm, which includes the near-infrared spectrum. This makes it suitable for applications such as optical imaging, beam shaping, and light collimation in systems that use infrared light.

The lens is made of N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, which provides anti-reflection properties, reducing unwanted reflections and increasing transmission.

The lens's geometry is spherical, with a radius of curvature of -78.298mm on the concave surface. The lens is unmounted, providing flexibility for integration into various optical systems.
