SLB-20-120PIR2 20.0 mm Dia. x 120.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-120PIR2 is a Plano-Convex Lens with a diameter of 20.0 mm and a focal length of 120.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality material known for its excellent optical properties.
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 collection and focusing. The lens has a thickness of 2.0 mm at the edge and 2.8 mm at the center, providing a robust structure while maintaining a low profile.
The SLB-20-120PIR2 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. It ensures high transmission and reduces reflection, making it ideal for applications that require optimal infrared transmission.
