SLB-50-90NIR2 50.0 mm Dia. x -90.0 mm FL; Coated; Plano-Concave Lens 750-1550nm

The SLB-50-90NIR2 is a Plano-Concave Spherical Lens, sourced from the renowned optical component manufacturer, OptoSigma. This lens, with a 50.0 mm diameter and a focal length of -90.0 mm, is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared applications.

The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible and near-infrared spectrum. The lens's geometry features a thickness of 10.3mm at the edge and 3mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The radii of curvature are -46.71mm for the front surface and 0mm for the rear surface, contributing to its Plano-Concave shape.

The SLB-50-90NIR2 is equipped with an Opt IR2 coating on both the front and back surfaces. This anti-reflection coating is specifically designed for the 750-1550nm wavelength range, further enhancing its performance in near-infrared applications by reducing surface reflections and improving transmission.
