I made the optimization of the telescope from OPO transmission to AMC. The entry is here. From my impression, I feel I move both lenses quite a lot. I just checked the position difference before and after optimization. I also compared the final implementation scheme with the initial design. The result is attached as the following form.
| lens1(holes=2.5cm) | lens2(holes=2.5cm) | |
| design position | 3.16 | 25.68 |
| first-time implementation position | 2.2 | 25.9 |
| final implementation position | 3.1 | 23.4 |
1. The position of the lens is relative to 'the dichroic mirror after OPO'
2. I assume that the beam waist inside OPO is 2 holes away from 'the dichroic mirror after OPO'
I am sorry that all the design work of Eleonora Polini should be done again because I moved this lens.
