SLB-10-20N 10.0 mm Dia. x -20.0 mm FL; Plano-Concave Lens Uncoated
The SLB-10-20N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from OptoSigma. This lens is uncoated and features a base shape of a circle, with a diameter of 10.0 mm. The lens's geometry includes a thickness edge of 3.3 mm and a thickness center of 2.0 mm, making it a robust and durable option.
The effective focal length (EFL) of this lens is -20.0 mm, indicating its concave nature. The radius of curvature (R1) is -10.38 mm, and the back focal length (BFL) is -21.3 mm. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens is designed to operate at a wavelength of 546.1 nm. It's important to note that the lens does not come with any coating, which may affect its performance in certain applications. However, its uncoated state can be advantageous in applications where coatings may introduce unwanted reflections or interferences.
