Detailed Description

50W / 55W High Power Laser Diode Module 940nm 105m For Material Processing This series of products build upon the foundation of multi-emitter coupling technology, high brightness fiber coupling and simplified packaging. With fiber core diameters as small as 105um for fiber coupling, BWT has advanced the laser brightness. In multi-single emitter diode laser, many improved optical designs have been patented. A key feature of these devices is low current which easy for current design. These compact packaging and commercially recognized formats allow easy integration into the existing products. Furthermore, some products can include integrated photodiode and thermistor, as well as thermoelectric cooler (TEC). The detachable fiber can be controlled via the fiber detector.
