Deskripsi Produk

1. Introduction

For the series of passive matching fibers manufactured by 3V TECHNOLOGY, their core is made of germanium doped quartz material and optical cladding is made of high purity quartz material. These materials are made into corresponding passive matching fiber products through precise geometric design and process control. This series of optical fibers are used to match rare earth-doped active fibers with low welding loss and good stability of laser output. They are widely used in industrial processing, scientific research, medical treatment, national defense and other fields, and can fully meet the application needs of all kinds of fiber laser users.
