- Surface type: Asphere with even terms Coeff.
- Seidel Aberration Coeff. to know the SPHA.
- Multi-Start to find the initial data
- MF Target: RMS Spot Radius with more real rays
In the last sample for singlet, we have got 43um spot size.
For more inforamtion, please visit: How to Design a Singlet?
We can find the seidel aberration coeff. to know that the main aberration is sphere aberration [SPHA].
The design is also from plane, but with conic as variables
The sag of asphere is:
For the asphere, we need more real rays sample to get small spot.
Click Multi-Start to find good initial data from plane
We got many choices.
Automatic to run DLS optimization
We can have differently result from different Multi-Start as show in the follow two picture.
We can also fix one surface.
We use the high order terms as variables.
Get perfect design.
