Fiber Collimation & Coupling Output Module
Mid infrared lasers have great advantages in highly sensitive gas detection, but unlike near-infrared lasers, most mid infrared lasers output spatial light. Therefore, the design and adjustment of the optical path are greatly restricted, which limits the application and promotion of mid infrared laser technology. With the emergence and gradual development of mid infrared optical fibers, it has become feasible to transmit mid infrared lasers through optical fibers.
By utilizing the latest mid infrared fiber and laser coupling technology, Kongtum Technology can help users couple the mid infrared laser output from space into the fiber, or directly provide the coupled tail fiber to output the mid infrared QCL laser, making the use of mid infrared lasers more convenient.
KONGTUM Technology has optical design capabilities and can customize optical collimation coupling devices with specific requirements such as mid infrared, large spot, and zoom.
