SLB-15-80NM 15.0 mm Dia. x -80.0 mm FL; Coated; Plano-Concave Lens 400-700nm
This is a Plano-Concave Lens, type SLB-15-80NM, sourced from OptoSigma. The lens has a diameter of 15.0 mm and a focal length of -80.0 mm, making it a negatively powered lens. The lens is made of n-bk7 schott material, a popular choice for its high Abbe number and low dispersion.
The lens's geometry includes a thickness edge of 2.7 mm and a thickness center of 2 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a flat surface on both sides. The lens's front and back are coated with opt m, a general-purpose coating that enhances the lens's performance in the 400-700nm wavelength range.
The lens is designed for use in the visible light spectrum, with a central wavelength of 546.1 nm. It is a spherical lens, meaning it has a curved surface that is a portion of a sphere. This type of lens is often used in optical systems because of its simple design and versatility.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website, which is provided in the item data.
