49-910 18.0mm Dia. x 22.5mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 49-910 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, boasting a diameter of 18.0mm and a focal length of 22.5mm. This lens is specifically designed for use within the near-infrared spectrum, between 600-1050nm, making it ideal for a range of applications within this wavelength range.
The lens is constructed from n-SF11 Schott, a high-index glass with excellent transmittance in the NIR region. The front and back surfaces of the lens are coated with the EDM NIR-I Standard Curve coating, which is designed to enhance the lens' performance within the near-infrared spectrum. This coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the system in which the lens is used.
The lens has a center thickness of 4mm and an edge thickness of 1.53mm, providing a robust and durable design. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface. The lens' effective focal length (EFL) is 22.5mm, and the back focal length (BFL) is 20.26mm.
