G063061322 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-50mm 450-700nm

This is a G063061322 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is a symmetric concave-concave type, featuring a base shape of a circle. It has a diameter of 22.4 mm and a center thickness of 1.5 mm, making it a compact and robust option for various applications.

The lens has an effective focal length (EFL) of -50mm, indicating its double-concave nature. This characteristic is further emphasized by its first and second radii of curvature, R1 and R2, which are -52.33 mm and 52.33 mm respectively. The lens's inner and outer radii are both zero, suggesting a uniform curvature throughout.

The lens is made of N-BK7, a popular material in the optical industry due to its excellent optical properties. This material is sourced from Schott, a leading glass manufacturer, ensuring high quality and reliability.

The lens is designed to operate within the wavelength range of 450-700nm, making it suitable for use in a wide range of applications, including but not limited to, fluorescence microscopy, machine vision, and other life science applications.

The lens comes with a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2visnbk7, is specifically designed to minimize reflection losses and enhance transmission within the specified wavelength range.
