Defines the wavelengths that can be used by default in the "handy calculations" pages. Refraction indexes are computed at the wavelength lam when they are specified by a reference of a glass catalog and when the wavelength is not an input parameter of the page. Refraction indexes defined by a reference of a glass catalog are calculated at the wavelengths lam_min and lam_max in the "chromatic aberration" pages.
