constitute such as Optical Isolator and Optical Circulator and other Laser devices of the important components, the device by the Optical Fiber and focusing Lens precise alignment. It can be the Optical Fiber output beam collimated, or collimated beam into the Optical Fiber. According to the output mode, the Collimator can be divided into non-expanded beam Collimator and expanded beam Collimator. Non-expanded beam Collimator by the Optical Fiber and focusing Lens components, the structure is simple, light weight, often used in Optical Fiber Laser systems in the beam collimation or coupling. Non-expanded beam Collimator can be divided into conventional and direct fusion type, direct fusion type will be Optical Fiber and Lens (fused quartz material) direct fusion, compared to conventional Collimator, its reliability is higher, can withstand higher power Laser. The expanded beam Collimator consists of Optical Fiber, focusing Lens and Beam Expander. The output beam has a small divergence angle and is usually used in large spot output systems. We provide Collimator, can choose active Optical Fiber, passive Optical Fiber, Polarization‑Maintaining Fiber (PMF) Optical Fiber, non-Polarization‑Maintaining Fiber (PMF) Optical Fiber, Wavelength range 980nm-2000nm, the use of high-quality Optics components, with simple and reliable mechanical structure, with a divergence angle of small, working distance long, high damage and other characteristics. All kinds of specifications QCS connector, special parameter requirements can also be customized according to customer needs.
