OptoSigma presents the SLB-25.4-80PIR2, a Plano-Convex Lens designed with a diameter of 25.4 mm and a focal length of 80.0 mm. This lens is specifically coated for the infrared spectrum, making it ideal for applications within the 750-1550nm range.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a center thickness of 3.9 mm and an edge thickness of 1.9 mm, providing a robust structure while maintaining a low profile.
The front and back surfaces of the lens are coated with Opt IR2, a coating specifically designed for infrared applications. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a simple, straightforward design. The effective focal length (EFL) is 80 mm, and the radius of curvature (R1) is 41.52 mm. The back focal length (BFL) is 77.4 mm.
