67-528 18.0mm Dia. x 36.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, specifically designed for use in the Near-Infrared II (NIR II) spectrum, with a diameter of 18.0mm and a focal length of 36.0mm. The lens is sourced from Edmund Optics, a renowned vendor in the optical industry.
The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the NIR region. The base shape of the lens is circular, and it features a spherical geometry. The lens has an inner radius of 0 and an outer radius of 0, indicating a uniform curvature. The thickness at the edge of the lens is 1.76mm, while the thickness at the center is 5mm. The effective focal length (EFL) of the lens is 18mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to optimize the lens' performance in the NIR II region, specifically between 750nm and 1550nm. The coating ensures high transmittance and minimal reflectance, making it ideal for applications such as biomedical imaging, night vision, and spectral analysis.
