SLB-50-100NM 50.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 400-700nm
The SLB-50-100NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 50.0 mm, is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens features a base shape of Circular geometry, with a center thickness of 3mm and an edge thickness of 9.4mm. The effective focal length (EFL) is -100mm, and the front and back radii are -51.9mm and 0mm respectively. The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The SLB-50-100NM is coated with an Opt M coating on both the front and back surfaces, enhancing its performance in the specified wavelength range. This coating helps to reduce reflection and increase transmission, thereby improving the overall efficiency of the optical system in which it is used.
Please note that the lens is spherical in shape, which may cause spherical aberration in certain applications. However, this can often be corrected with the use of additional optical elements.
