Wavelength:878.6nm Output power: 170W Fiber core diameter: 200μm Optical fiber numerical aperture:0.22 Feedback protection: 1020nm-1200nmInstructions for use
- 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. - Soldering point should be closeto the middle of the pins. Soldering temperature should be lower than 260℃ and time shorter than 10 second. PRODUCT PARAMETERSSpecifications (25°C) | Symbol | Unit | Minimum | Typical | Maximum | |
