SLB-25.4-80NIR1 25.4 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

This is a Plano-Concave Spherical Lens, model SLB-25.4-80NIR1, manufactured by OptoSigma. The lens has a diameter of 25.4 mm and a focal length of -80.0 mm, making it suitable for a variety of optical applications. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. The curvature of the concave side is defined by a radius of -41.52 mm. The lens has an edge thickness of 4 mm and a center thickness of 2 mm, providing structural integrity and minimizing optical aberrations.

The SLB-25.4-80NIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the 633-1064nm wavelength range, reducing reflection and increasing transmission. The lens is currently in stock and available for immediate purchase through the provided weblink.
