SLB-25.4-90NIR1 25.4 mm Dia. x -90.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-25.4-90NIR1 is a plano-concave lens with a diameter of 25.4 mm and a focal length of -90.0 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 optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry includes a thickness edge of 3.8 mm and a thickness center of 2 mm. The inner and outer radii are both zero, indicating a circular shape. The front and back surfaces of the lens are coated with opt IR1, a broadband anti-reflection coating that enhances transmission in the 633-1064 nm range. This coating reduces surface reflections, improving the overall efficiency and quality of the optical system.

The lens is designed for use in the visible and near-infrared regions of the spectrum, making it suitable for a wide range of applications. Its plano-concave shape and broadband coating make it an ideal choice for systems requiring high transmission and low reflection. The lens is currently in stock and available for immediate purchase.
