SLB-50-70NIR1 50.0 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

OptoSigma presents the SLB-50-70NIR1, a Plano-Concave Spherical Lens with a diameter of 50.0 mm and a focal length of -70.0 mm. This lens is designed for use within the wavelength range of 633-1064nm, making it suitable for near-infrared (NIR) applications.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The Plano-Concave geometry, characterized by one flat surface and one curved surface, is ideal for applications requiring light collimation or reduction of beam divergence.

The SLB-50-70NIR1 features a front and back coating of opt IR1, which is specifically designed for the infrared spectrum. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.

The lens has a thickness of 13 mm at the edge and 3 mm at the center, providing structural rigidity while minimizing unnecessary weight. The inner and outer radii are 0 mm, indicating a simple, straightforward design that is easy to integrate into optical systems.

This lens is currently in stock and available for immediate purchase through the OptoSigma website. With its high-quality materials, advanced coatings, and precise geometry, the SLB-50-70NIR1 is an excellent choice for a wide range of NIR applications.
