SLB-20-70PIR2 20.0 mm Dia. x 70.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-70PIR2 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens boasts a diameter of 20.0 mm and a focal length of 70.0 mm, making it suitable for a wide range of optical applications. The lens is made from n-bk7 schott, a high-quality optical glass, ensuring excellent light transmission and image quality.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). This design allows for efficient light gathering and focusing, making it ideal for use in imaging systems, beam shaping, and other optical applications. The lens has a thickness of 2.0 mm at the edge and 3.4 mm at the center, providing robustness and durability.
The SLB-20-70PIR2 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.
