Quality Assurance

Vertical integration is the key to manufacturing better optical and optomechanical products and our focus on QA is the key to delivering them to you with guaranteed performance.

You can depend on components with guaranteed performance, because quality is a company-wide relentless focus at Coherent. From looking at scratch and dig on every lens, to dropping our ultrafast lasers from a forklift to check they are safely packaged for shipping.
