SLB-25-60NM 25.0 mm Dia. x -60.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-25-60NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, with a diameter of 25.0 mm and a focal length of -60.0 mm. This lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens is made from n-bk7 schott, a high-quality optical glass, and features a spherical geometry. The curvature of the lens is defined by a radius of 31.14 on the front surface, and the lens has a thickness of 4.6mm at the edge and 2mm at the center. The back surface of the lens is flat.
The SLB-25-60NM is coated with an Opt M coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
