Day 1 on the Optical Engineer path.

What a Optical Engineer does

Designs and tests optical parts and systems for products like cameras, sensors, and lasers so they meet image and measurement goals.

  • Design lenses, mirrors, and optical paths to meet image or measurement requirements
  • Model optical performance and tradeoffs using simulation and calculations
  • Build and align prototypes, then measure focus, distortion, and light efficiency
  • Select materials, coatings, and tolerances for cost, durability, and performance
  • Write test plans and run lab experiments to validate designs
  • Work with mechanical and electrical teams to integrate optics into hardware
  • Troubleshoot optical issues in prototypes or production and propose fixes

A day in the life

  1. Review requirements, tolerances, and open issues with the project team
  2. Run optical simulations, update designs, and document design decisions
  3. Spend lab time aligning optics and collecting test data on a prototype
  4. Meet with manufacturing to review build issues and adjust tolerances
  5. Summarize results and next steps in short reports and design reviews

Tools you will use
