This is a high-quality Plano-Convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, with the product code 88-785, has a diameter of 4.0mm and a focal length of 12.0mm, making it suitable for a wide range of optical applications.
The lens is made from the high-grade material n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens ideal for applications that require high image quality and color correction.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, which stands for Yttrium Aluminum Garnet Broadband Anti-Reflective, is designed to reduce surface reflections and increase transmission in the spectral range of 500-1100nm. This makes the lens particularly suitable for use in systems that operate in the near-infrared region of the spectrum.
The geometry of the lens includes a thickness of 1.19mm at the edge and 1.52mm at the center. The lens has a spherical shape with a radius of curvature of 6.22mm on the convex side. The back surface of the lens is flat.
The lens is currently in stock and available for immediate shipping. For more information, please refer to the vendor's website at https://www.edmundoptics.com/p/40mm-dia-x-120mm-fl-yag-bbar-coated-plano-convex-lens/31149/.
