Figure 2 The controls of M1x, M1y, M2x, M2y, M3x, M3y, G1 rotation, and G2 rotation are on Newport XPS_1 (mcn-mec-las1). The control of G2 translation is on Newport XPS_2 (mcn-mec-las2)
Alignment
Assuming x3 telescope has aligned and the beam is at the center of CompInFF.
...
- The camera CompG2 is looking at the surface of the second grating. For alignment check, it can confirm both top and bottom beams on G2 are centered on crosshairs set by the camview. Additional information like spectral profile can be obtained by using the lineout function in the camview.
