SLB-10B-50NM 10.0 mm Dia. x -49.7 mm FL; Coated; Double-Concave Lens 400-700nm
The SLB-10B-50NM is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed for use within the wavelength range of 400-700nm, is made of the renowned material n-BK7 Schott, ensuring excellent optical performance.
The lens boasts a diameter of 10.0 mm and a center thickness of 2.0 mm, with an edge thickness of 2.5 mm. The double-concave design, characterized by radii of curvature -51.9 mm for the front surface and 51.9 mm for the back surface, results in a back focal length of -50.3 mm. This configuration provides a negative focal length, making it suitable for various applications requiring image reduction or diverging light paths.
The SLB-10B-50NM features an antireflection coating on both the front and back surfaces, specifically optimized for the wavelength range of 400-700nm. This coating reduces surface reflections, enhancing the overall transmission and improving the overall performance of the lens in its intended application.
