SLB-40-80NIR2 40.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 750-1550nm

The SLB-40-80NIR2 is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of -80.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared (NIR) applications.

The lens is made from n-bk7 schott, a popular material in optical systems due to its excellent optical properties and versatility. The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. This particular design is often used to diverge or spread out light, making it ideal for various applications such as beam expansion or collimation.

The SLB-40-80NIR2 comes with a front and back coating of opt ir2. Coatings are applied to the surface of optical components to enhance their performance. In this case, the opt ir2 coating is designed to improve the lens's performance within the 750-1550nm wavelength range.

The lens has an inner radius of 0 and an outer radius of 0, indicating it is a simple lens without any additional features such as threads or mounts. The edge thickness is 7.1 and the center thickness is 2, providing a good balance between durability and weight.
