Technical content
The QBH fiber optic cable is the no.1 fiber interface for industrial high-power lasers. It’s a well proven standard compatible with most available tools world-wide. The QBH fiber connector is water-cooled to optimize the performance, including its superior power loss capability. The built-in mode stripper generates a well-defined beam without any cladding power. With the reinforced and extremely durable fiber hose it is well-suited for dynamic robot applications. QBH FIBER OPTIC CABLE Beam Delivery Components
