G314301322 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm 450-700nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 22.4 mm. The center thickness of the lens is 1.5 mm, and it has an effective focal length (EFL) of -40 mm, making it a negatively powered lens. The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties.
The lens is designed to work within the wavelength range of 450-700 nm, which covers the visible light spectrum. It comes with a broadband anti-reflection coating, specifically the Qio Bbar Arb2visnbk7 coating, on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the lens's performance in its intended wavelength range.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple plano-concave design. The curvature of the concave surface is -20.833 mm.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed information, you can refer to the provided weblink.
