| Who should attend: Engineers who need to learn optical design theory, principles, and the use of the ZEMAX Optical Design Program. This course covers first and third order theory, imaging properties, glass properties and selection, and classical design techniques. |
| Attendees will learn how to use ZEMAX, including defining optical systems, constructing merit functions, and performing optimizations. Diagnostic tools are also covered. |
| This is the perfect course for those who need a basic knowledge about optical system theory and design. |
| You do not need any prior knowledge of optical design or ZEMAX to benefit from this class. |
