SLB-40-100NIR1 40.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-40-100NIR1 is a Plano-Concave Spherical Lens, precision engineered by OptoSigma. This lens boasts a diameter of 40.0 mm and a focal length of -100.0 mm, making it ideal for a wide range of optical applications. The lens is constructed from n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens geometry is meticulously designed, with an edge thickness of 6.0 mm and a center thickness of 2.0 mm. The inner and outer radii are 0 mm, indicating a flat surface on both sides of the lens. The lens's effective focal length (EFL) is -100.0 mm, and the back focal length (BFL) is -101.3 mm. The curvature of the lens is defined by a radius of -51.9 mm on the concave side.
The SLB-40-100NIR1 is coated with Opt IR1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating ensures high transmission and low reflection, making the lens suitable for use in lasers, beam expanders, and other optical systems.
