The SLB-30-200NIR1 is a Plano-Concave Spherical Lens, 30.0 mm in diameter and featuring a focal length of -200.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made from n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens's geometry includes a thickness edge of 3.1 mm and a thickness center of 2 mm, providing a robust structure. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The lens's effective focal length (EFL) is -201.3 mm, and its radius of curvature (R1) is -103.8 mm.
The SLB-30-200NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating ensures optimal transmission and reduces reflection, making it suitable for various applications, including laser systems and imaging applications.
