G313217000 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm Uncoated
This is a G313217000 22.4 mm Dia. N-BK7 Double-Concave Lens, with a focal length (EFL) of -150mm, sourced from Qioptiq Photonics. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. This material has a high refractive index and low dispersion, making it ideal for a wide range of applications. The lens's double-concave shape, with radii of curvature R1=-156.22mm and R2=156.22mm, contributes to its negative focal length.
The lens has a diameter of 22.4mm and a center thickness of 1.5mm. The inner and outer radii are both zero, indicating that the lens's edges are straight and not curved.
This lens is designed to operate at a wavelength of 588nm. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is used with.
