Product Development Process


Working with the whole team at Gray Optics has been a very pleasant experience. They are a very knowledgeable and professional group that provided critical design assistance. With their help, our device saw a leap in performance that exceeded expectations and I look forward to working with them again on future projects.

The Gray Optics team have worked closely with us to develop a new medical camera. I was first impressed with the accuracy and reliability of their optical engineering services. Based on a positive first interaction, I have expanded their role significantly, knowing that the technical research, testing and evaluation, and thoughtful advice they provide is essential for the success of our project. And that says it pretty well! With Gray Optics, I feel it’s “our project”.

It is rare to find a standout talent and communicator like Dan. I had the pleasure of working with Gray Optics on two challenging projects in product miniaturization and wide-field, high-resolution microscopy. Our collaboration achieved many exciting firsts. Dan was great at strategic planning and had the grit and resourcefulness to facilitate the development of a robust, easy-to-integrate solution. Dan is an accomplished optics expert and doubles as a fantastic mentor: taking the time to explain specialized analytical concepts in a relatable way. His strong attention to detail has been valuable when technical challenges arise and we have thorough documentation for why and how we went about design iterations. Dan is a highly recommended professional.
