What Our Clients Say After Taking This Course

• "The class helped me put together a lot of things I've learned over the last year on how our projectors work. This will help me better address how to solve customer problems and how to evaluate new projector designs." Product Engineer, Digital Projectors

• "The course gives me a better awareness of optical problems to look out for during prototyping and product development of projectors. This will help me to identify problems early on in the product development cycle." Mechanical Engineer

• "I needed an overview of the design concerns and how they affect performance. Your translations from verbiage (technical buzzwords) to geometric diagrams was most helpful. You were really good at making a very technical subject matter understood." Supply Chain Manager

• "Allowed me to get a good foundation on the basics of optics and illumination in projectors. The words, vocabulary, concepts, and critical parameters for future design were very helpful. You provided some potential quality issues to measure and specify." Reliability Engineer

• "When there are customer requirement that are related to illumination and optics, I will have a better understanding of the system. I liked the flow of the course, use of humor, and the show and tell items - Great Job!" New Product Development Manager

• "Instruction was clear! Samples of lenses, light engine, and modulator and the part they play in projector are excellent. Excellent class!" Opto-Mechanical Technician

• "This class will help me as a product engineer because it enables me to understand design changes in the optical system of a projector and the implications, in terms of reliability and quality, of these changes." Product Engineer, Digital Projectors

• "A lot of good information for understanding system level trade-offs between modulators and optical system, very useful course. Would recommend that anyone joining projector projects to take this course." Product Development Manager

• "This is a great overview as I am in the process of transferring from "X" group to the "Y" group. My experience is in IC's and fab processing, so I didn't have a systems understanding until I took this course." Senior Fabrication Process Engineer
