SLB-25.4-60NIR2 25.4 mm Dia. x -60.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-25.4-60NIR2 is a Plano-Concave Spherical Lens, designed with a 25.4 mm diameter and a focal length of -60.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made from n-bk7 schott material, a popular choice due to its excellent optical properties and versatility.
The lens's geometry is meticulously crafted, with an edge thickness of 4.7 mm and a center thickness of 2 mm. The inner and outer radii are 0 mm, indicating a flat surface on one side and a concave surface on the other. The back focal length is -61.3 mm, slightly longer than the focal length, which is typical for Plano-Concave lenses.
The SLB-25.4-60NIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating is specifically designed to optimize the lens's performance in the near-infrared spectrum, making it an ideal choice for applications in this range.
