SLB-30-170NIR1 30.0 mm Dia. x -170.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-30-170NIR1 is a Plano-Concave Spherical Lens, 30.0 mm in diameter, with a focal length of -170.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality optical glass, and features a Plano-Concave geometry, making it ideal for a wide range of applications.
The lens has a center thickness of 2 mm and an edge thickness of 3.3 mm, ensuring durability and stability. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of -88.23 mm on the curved side. The back focal length is -171.3 mm, slightly longer than the focal length due to the lens's concave shape.
The SLB-30-170NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating reduces reflection and increases transmission, making the lens suitable for use in laser systems and other applications where high transmission is required.
