Table 10 - Concave Holographic Reflectance Gratings
 |
For the gratings listed in Parts A and B of this table, the figure at left defines the following parameters:
| a |
incidence angle |
| r |
distance from entrance slit to grating center |
| b |
diffraction angle |
| r' |
distance from grating center to image |
The angles a and b are measured from the grating normal; their algebraic signs are opposite if they lie on opposite sides of the normal.
