Hello everyone,
I am new to optical design and currently working on designing a simple objective using two achromatic lenses. The objective should have:
- Effective focal length (EFL): 40 mm
- Working distance (WD): 200 mm
- Magnification: 5X (using a 200 mm tube lens)
I am trying to ensure that the working distance remains fixed during optimization. My question is:
- How can I constrain the working distance in the optimization process?
- Is there a specific operand in Zemax (or another software) that I should use to maintain the WD?
My ultimate goal is to design a confocal microscope with this working distance requirement.
I would appreciate any guidance or suggestions!
Thanks in advance,
Rasoul
