Caution
Fill in all input cells.
Choose all parameters unit.
n can be either a numeric value or the reference of a glass from the catalog. If a reference of a glass is selected, the calculation considers the refraction index of this glass at the wavelength lam defined in the current page. In this case, note that no is a numeric value that may not correspond to the refraction index of the selected glass at the defined wavelength.
All parameters are positive.
