Thank you for your optics design. I am very happy to inform you that the optical lens works great. We used it in our optical system and the performance improved about three times! You advised us with the best solution, so that we met the project goals as well as the budget. We are grateful to work with a professional and responsible company like yours.
Your designing work is among the best per our cooperative experience with optical companies. And we definitely will choose you as our next project partner. Thanks again!
