SLB-25-100NIR1 25.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-25-100NIR1 is a Plano-Concave Spherical Lens, 25.0 mm in diameter, with a focal length of -100.0 mm, sourced from OptoSigma. This lens is designed for use with wavelengths between 633 and 1064nm, making it suitable for a range of applications in the near-infrared spectrum.
The lens is made from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The Plano-Concave geometry, with a center thickness of 2mm and an edge thickness of 3.5mm, is designed to refract light without introducing spherical aberration. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the surface.
The lens features a coating of Opt IR1 on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in the near-infrared range, reducing reflection and increasing transmission. The coating status is currently in stock, according to the vendor's website.
