SLB-50.8-100NIR2 50.8 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
OptoSigma offers the SLB-50.8-100NIR2, a Plano-Concave Spherical Lens with a diameter of 50.8 mm and a focal length of -100.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared 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's geometry includes an edge thickness of 9.6 mm and a center thickness of 3 mm, contributing to its robust construction. The inner and outer radii are both 0 mm, indicating a uniform curvature.
The SLB-50.8-100NIR2 features a coating of opt ir2 on both the front and back surfaces. This coating enhances the lens's performance within its specified wavelength range, providing improved transmission and reduced reflection.
