SLB-10-15NIR2 10.0 mm Dia. x -15.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-10-15NIR2 is a plano-concave lens with a diameter of 10.0 mm and a focal length of -15.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for its high-quality optical elements. The lens is made of n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties.
The lens features a front and back coating of opt IR2, which is specifically designed for use in the 750-1550nm wavelength range. This coating enhances the lens' performance in the near-infrared spectrum, making it ideal for applications that require high-performance in this range.
The geometry of the lens includes a thickness edge of 3.8 mm and a thickness center of 2 mm. The lens' inner and outer radii are both 0, indicating a flat surface on both sides with a concave curvature in the middle. The effective focal length (EFL) of the lens is -15.0 mm, and the back focal length (BFL) is -16.3 mm.
This lens is a spherical lens, meaning it has a spherical surface. The curvature of the lens is defined by a radius of -7.79 mm on the concave side. The lens is designed to be used with a wavelength of 546.1 nm.
