SLB-10B-15NIR2 10.0 mm Dia. x -14.7 mm FL; Coated; Double-Concave Lens 750-1550nm
The SLB-10B-15NIR2 is a high-quality double-concave lens offered by OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens features a base shape of a circle with a diameter of 10.0 mm and is made from the popular material n-BK7 Schott.
The lens has a center thickness of 2.0 mm and an edge thickness of 3.6 mm, providing a robust structure suitable for various applications. The effective focal length (EFL) is -14.7 mm, and the back focal length (BFL) is -15.3 mm, indicating a strong converging capability.
The double-concave geometry of this lens is defined by radii of curvature R1 (-15.57 mm) and R2 (15.57 mm), which contribute to its unique optical properties. The lens's design includes an inner radius of 0 mm and an outer radius of 0 mm, ensuring consistent performance.
The SLB-10B-15NIR2 lens comes with OptoSigma's proprietary Opt IR2 coating on both the front and back surfaces. This anti-reflection coating is specifically designed for the 750-1550nm wavelength range, minimizing surface reflections and increasing overall transmission.
