SLB-20-100NIR1 20.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-20-100NIR1 is a Plano-Concave Spherical Lens, precision crafted by OptoSigma, a leading vendor in the optical industry. This lens boasts a diameter of 20.0 mm and a focal length of -100.0 mm, making it ideal for a wide range of applications.

The lens is made from n-bk7 schott, a high-quality material known for its excellent optical properties. The base shape is circular, and the lens features a Plano surface on one side and a concave surface on the other. The center thickness of the lens is 2.0 mm, while the edge thickness is 3.0 mm, providing robustness and durability.

The lens 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 laser applications.

The geometry of the lens is precisely designed, with an inner radius of 0 mm and an outer radius of 0 mm. The effective focal length (EFL) is -101.3 mm, and the radius of curvature (R1) is -51.9 mm. These parameters ensure the lens delivers high-quality, distortion-free images.
