G052308331 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-50mm
This is a mounted plano-concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular material in the optical industry due to its excellent optical properties. The effective focal length (EFL) of this lens is -50mm, indicating that it is a diverging lens, causing incoming light rays to spread out after passing through it.
The lens's geometry includes a center thickness of 1.5 mm and a radius of curvature (R1) of -26.039 mm for the curved surface. The lens's design is spherical, which is a common shape for optical lenses due to its ease of manufacturing and good optical performance.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the lens's performance in various applications.
The lens is designed to operate at a wavelength of 588 nm. This wavelength falls within the visible light spectrum, suggesting that this lens could be used in applications involving visible light.
