reflective grating


relation between incident and diffracted wave tilts for a reflective grating


Caution
Fill in all input cells.
Choose all parameters unit.
n can be either a value or the reference of a glass from the catalog.
Diffraction order k and angles are algebric.
Angle positive way is counterclockwise according the round arrow in the bottom right of the scheme.
