SLB-30-2000PM 30.0 mm Dia. x 2000.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-30-2000PM is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 2000.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens's geometry is characterized by a thickness of 2.0 mm at the edge and 2.1 mm at the center. The inner and outer radii are both zero, indicating a circular shape. The effective focal length (EFL) is 2000.0 mm, and the back focal length (BFL) is 1998.6 mm. The radius of curvature (R1) is 1038 mm.
The SLB-30-2000PM is coated with Opt M on both the front and back surfaces, enhancing its performance in the wavelength range of 400-700nm. This coating improves the lens's transmission and reduces reflection, making it suitable for various applications in this spectral range.
