SLB-25.4-80NIR2 25.4 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
This is a Plano-Concave Lens, type SLB-25.4-80NIR2, sourced from OptoSigma. It is designed for use in the 750-1550nm wavelength range, making it suitable for near-infrared applications. The lens has a diameter of 25.4mm and a focal length of -80.0mm, offering a high level of optical performance.
The lens is made from n-bk7 schott, a material known for its excellent optical properties. It features a spherical shape, with a front radius of curvature (R1) of -41.52mm and a back focal length (BFL) of -81.3mm. The lens has an edge thickness of 4mm and a center thickness of 2mm, providing robustness and durability.
The lens is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating reduces reflection and increases transmission, improving the overall efficiency of the optical system.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
