Hi everyone,

I am in the process of designing a continuous zoom system with magnifications ranging from 3x to 5x. However, I have encountered some challenges in meeting the desired specifications.

Here are the basic requirements for the system:

  • Working Distance: 500mm
  • Field of View (FOV): 80 - 100 mm
  • Total Optical Tube Length Requirement (TOTR): 50-60 mm (for the lens system)
  • Objective Diameter: 18 mm
  • Eyepiece Diameter: 12 mm

I have initiated the design, but I'm facing issues such as achieving the required FOV and encountering image blurring.

I have attached my initial design for your reference.

I would greatly appreciate any guidance, suggestions, or insights on how to proceed with this design. Your expertise and advice will be invaluable in helping me overcome these challenges and achieve the desired performance for the continuous zoom system.
