SLB-25.4-90NM 25.4 mm Dia. x -90.0 mm FL; Coated; Plano-Concave Lens 400-700nm

OptoSigma presents the SLB-25.4-90NM, a Plano-Concave Spherical Lens designed with a 25.4 mm diameter and a focal length of -90.0 mm. This lens is specifically coated for use within the wavelength range of 400-700nm, making it suitable for various applications within the visible light spectrum.

The lens is fabricated from the renowned N-BK7 glass by Schott, a material well-known for its excellent optical properties. The Plano-Concave geometry, characterized by a flat front surface and a curved back surface, is designed to refract and diverge light. The lens's center thickness is 2mm, while its edge thickness measures 3.8mm, providing robustness and durability.

The front and back surfaces of the lens are coated with Opt M, a coating that enhances the lens's performance within its specified wavelength range. The coating reduces surface reflections, improving transmission and overall system efficiency.

This lens is currently in stock and available for immediate purchase through the OptoSigma website. With its high-quality construction, precise geometry, and optimal coating, the SLB-25.4-90NM is an excellent choice for a wide range of optical systems and applications.
