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.
