 Determines the optical parameters and quality of a doublet lens for astronomical refractors - RC index parameters from one or two known glasses. If you know one lens material, you can use the simple method (RCindex_universal), or if you know both lenses (RCindex_2_lenses), you can enter refractive indexes from the glass catalogue of manufacturers such as Ohara, Schott and others. The program determines lenses such as Achromat, semi Apochromat or Apochromat and their parameters. | |
