3.3 Wavelength

The Wavelength inputs allows the user to enter the wavelength range over which the user can model. The unit of measurement is nanometers. Default values are 420nm to 700nm (visible spectrum). Sampling steps below 1nm can result in long execution times. A 2nm step is good as this provides accuracy and relatively fast computational speeds for a majority of applications.
