G313217322 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm 450-700nm
This is a G313217322 Double-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a base shape of a circle and is designed for use in the 450-700nm wavelength range.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. It has a diameter of 22.4mm and a center thickness of 1.5mm. The lens's effective focal length (EFL) is -150mm, indicating its concave nature.
The lens's geometry is characterized by its first and second radii (R1 and R2), which are -156.22mm and 156.22mm respectively. These radii contribute to the lens's double-concave shape. The lens's inner and outer radii are both zero, indicating a symmetrical design.
The lens features a coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is designed to enhance the lens's performance in the visible light spectrum.
