Product Features:
The fiber laser pump source independently developed by BWT has been put on the market for nearly 20 years. Has a good reputation. BWT's Optical Fiber Division is also a customer of the Semiconductor Division. BWT fiber lasers all use self-developed pump sources. In the early stage of product processing, BWT will inspect suppliers in many aspects and select high-quality raw materials. To ensure the stable performance of the output products, long-term reliability. In addition to mass products, the high-quality R&D team can also meet the personalized customization needs of customers.Main Features
Wavelength：793nm Output power: 180W Fiber core diameter: 200μm Optical fiber numerical aperture：0.22 NA Applications: Fiber laser pump sourceInstructions for use
- Avoid eye and skin exposure to direct radiation during operation. - ESD precautions must be taken during storage, transportation and operation. - Short-circuit is required between pins during storage and transportation. - Please connect pins to wires by solder instead of using socket when operation current is higher than 6A.PRODUCT PARAMETERS
