SLB-30B-30NIR2 30.0 mm Dia. x -29.7 mm FL; Coated; Double-Concave Lens 750-1550nm
The SLB-30B-30NIR2 is a high-quality double-concave lens, designed and manufactured by OptoSigma. This lens, with a diameter of 30.0 mm and a focal length of -29.7 mm, is made from the renowned material n-BK7 Schott, ensuring durability and reliability.
The lens features a unique double-concave geometry, with radii of curvature of -31.14 mm for the first surface and 31.14 mm for the second surface. This particular design allows for precise control over the light path, making it ideal for a wide range of applications, particularly in the infrared spectrum between 750nm and 1550nm.
The SLB-30B-30NIR2 comes with a broadband anti-reflection coating, Opt IR2, on both the front and back surfaces. This coating is specifically designed to reduce surface reflections and increase transmission in the 750-1550nm range, further enhancing its performance in infrared applications.
