The laser (QBH) fiber output device is a component that expands the fiber spot and reduces power density by fusion splicing the fiber to a quartz pillar and packaging it with mechanical parts. It is mainly made of high-quality quartz glass and is commonly used for medium-to-high power continuous beam divergence output in metal cutting or welding applications.
Our QBH quartz end caps can withstand high power, are compatible with various fiber types, and have a wide range of applications. Custom processing is available according to your dimensional requirements.
