G063873331 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-200mm
This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -200mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high transmittance in the visible spectrum.
The lens's geometry includes a center thickness of 1.5mm and a radius of curvature (R1) of -104.41mm. The lens's inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The lens's spherical shape ensures high-quality imaging and light transmission.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections and increases light transmission, making it suitable for high-precision optical applications.
The lens is mounted, making it ready for immediate use in optical systems. The web link provided leads to the product page on Qioptiq's website, where you can find more information and check the current availability of the lens.
