SLB-15-80N 15.0 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated
The SLB-15-80N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from OptoSigma. This lens is uncoated and features a base shape of Circular. The lens has a diameter of 15.0 mm and a thickness edge of 2.7 mm, with a thickness center of 2.0 mm. The effective focal length (EFL) of this lens is -80.0 mm, making it a negative or diverging lens.
The lens's first radius (R1) is -41.52 mm, and the back focal length (BFL) is -81.3 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. The lens is made of n-BK7 Schott material, a common and reliable material in the optical industry due to its excellent optical properties and durability.
The lens is designed to operate at a wavelength of 546.1 nm. The shape of the lens is spherical, a common shape in optical lenses due to its ease of manufacturing and good optical performance. The lens does not come with any coating, which means it is in its raw state. Coatings are often applied to lenses to improve their optical performance or durability, but this lens is designed to be used without them.
