How Do You Optimize a Lens Design in Zemax for Different Units?

[johngreen21]

Homework Statement

Use Zemax to solve the lens splitting problem meeting the requirements listed out in notes a-d

Relevant Equations

EFL=4"*7.8=31.2"

I tried to lay out the lens design and MFE, but was not getting the results I should be.

I am stuck on which steps I need to do first and what operands to use with the specific variables. The problem is written in inches, but I've always used mm's so I am unsure If I need to convert or not.

Using Zemax for lens design can be overwhelming at first, but with some practice and understanding of the software, you will be able to solve this lens splitting problem. First, make sure you have all the necessary information such as the lens specifications, focal length, and desired performance.

Next, start by setting up your lens layout in Zemax. This includes defining the lens elements, their surfaces, and the material properties. Make sure to use the correct units, whether it is inches or mm, to avoid any conversion errors.

Once you have set up the lens layout, you can use the Merit Function Editor (MFE) to optimize the lens design. This involves defining the merit function, which is a mathematical expression that represents the desired performance of the lens. You can use operands and variables in the MFE to adjust the lens parameters and achieve the desired performance.

It is important to understand the different operands and their functions in Zemax, as they can greatly impact the optimization process. Some commonly used operands for lens design include radius, thickness, and glass type. You can also use the "Solve" feature in the MFE to automatically adjust the operands and find the best solution for your lens design.

If you are still unsure about which steps to take or which operands to use, I recommend referring to Zemax's user manual or seeking assistance from experienced Zemax users. With practice and patience, you will be able to successfully solve this lens splitting problem using Zemax.
