The SLB-20-100NM is a Plano-Concave Spherical Lens, a high-quality optical component sourced from OptoSigma. This lens, designed for use within the wavelength range of 400-700nm, is a circular element with a diameter of 20.0mm and a focal length of -100.0mm.
The lens's geometry is characterized by its edge thickness of 3.0mm and center thickness of 2.0mm. The front and back surfaces of the lens have a radius of curvature of -51.9mm and -101.3mm respectively, contributing to its plano-concave shape. The lens's inner and outer radii are both 0mm, indicating a uniform curvature across the lens's surface.
The lens is crafted from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens's coating, Opt M, is applied to both the front and back surfaces, enhancing its performance within the specified wavelength range.
