G063073331 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-150mm
This is the G063073331 model from Qioptiq Photonics, a 22.4 mm diameter N-BK7 mounted plano-concave lens with an effective focal length (EFL) of -150mm. The lens is spherical in shape, featuring a concave surface with a radius of curvature (R1) of -78.298mm. The lens's center thickness is 1.5mm.
The lens is made of N-BK7 glass, a common and highly versatile borosilicate crown glass with a refractive index of approximately 1.5168 at 588nm. This glass is known for its excellent homogeneity, low optical dispersion, and high transmittance in the visible and near-infrared regions.
The lens is coated with Qio AR Al RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, particularly at a 45-degree angle of incidence. The coating is suitable for a wavelength of 588nm.
The lens is mounted, making it ready for immediate use in optical systems. The vendor for this item is Qioptiq Photonics, a leading global supplier of photonic solutions for a wide range of applications. According to the vendor, the item is currently in stock and available for purchase.
