SLB-25.4-70PIR2 25.4 mm Dia. x 70.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-25.4-70PIR2 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm and a focal length of 70 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This geometry is often used in optical systems to focus or collimate light. The lens has a thickness of 1.9 mm at the edge and 4.2 mm at the center, providing structural integrity and optimal light transmission.
The SLB-25.4-70PIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 750nm and 1550nm, making it suitable for applications such as thermal imaging, night vision, and fiber optics.
The lens's design is circular, allowing it to be used in a wide range of optical systems. The inner and outer radii are 0, indicating a uniform curvature across the lens. The effective focal length (EFL) is 70 mm, and the back focal length (BFL) is 67.2 mm, providing a clear understanding of the lens's optical properties.
