SLB-50B-60NIR1 50.0 mm Dia. x -59.5 mm FL; Coated; Double-Concave Lens 633-1064nm
The SLB-50B-60NIR1 is a high-quality double-concave lens offered by OptoSigma, designed for use within the wavelength range of 633-1064nm. This lens is fabricated from the well-regarded material n-BK7 Schott, ensuring excellent optical performance and durability.
The lens boasts a diameter of 50.0 mm and a focal length of -59.5 mm, making it suitable for a wide range of applications. The edge thickness measures 13.5 mm, while the center thickness is a mere 3 mm, contributing to its compact design and efficient light transmission.
The SLB-50B-60NIR1 features a double-concave geometry with radii of curvature of -62.28 mm on both the front and back surfaces. This design allows for effective convergence or divergence of light, depending on the application. The back focal length is -60.5 mm, and both the inner and outer radii are 0 mm, indicating a uniform curvature throughout.
The lens is coated with Opt IR1 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating reduces surface reflections and improves overall transmission, making the SLB-50B-60NIR1 an excellent choice for various optical systems.
