• Doublet with BK7 and F2
• The chromatic aberration will be minized
• There are three sphere surface, so the SPHA will be also corrected. 
• The optimization will silde to the local vellay, but we can use the multi-start to find a better solution.
• MF target: EFL=100mm and RMS Spot Radius for all F D C wavelength 

 Open the initial data from the sample folder

Lens data 

The EPD is 25mm

F D C wavelength 

0 angle fileld

RMS Spot Radius MF and 100mm EFL

The 3D Layout

We can use the Multi-Start tool to find the initial data

Many samples can be the start point.

We got a good design.
