The SLB-30-4000PM is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 4000.0 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 effective focal length (EFL) is 4000.0 mm, and the radius of curvature (R1) is 2076.0 mm. The back focal length (BFL) is 3998.6 mm, and both the inner and outer radii are 0.0 mm.
The SLB-30-4000PM is coated with opt m on both the front and back surfaces, enhancing its performance in the 400-700nm wavelength range. This coating improves the lens's transmission and reduces reflection, making it suitable for various applications.
