If you have drawings on your hand, TOYOTEC, which operates Optical Design Engineering Navigator, will offer a price and lead time when we provide our quotation.
If no drawings are available but only specifications are available, TOYOTEC conducts a study of the creating drawings to meet the specifications before providing quotation.
As you can see, the process is slightly different if you have the drawings and if only specifications available.

In addition, we can also handle the case where only specifications are available.
While confirming the application and specifications with the customer, we can propose the most appropriate and specific product design through to manufacturing.

As you can see, we can handle both cases with and without drawings, and we can also handle only with the specifications, so please feel free to contact us if you have any concerns about design and manufacturing at various stages of development, such as when you are considering product concepts or product specifications. Please contact us for more information.
