1. Output power regulation can be achieved through digital or analog interfaces, with a range of 10% -110%. Suggested power range is 70% -110%.

2. Static adjustment accuracy, defined as relative to the right bottom edge, with the direction of light output as a reference

3.200mm is 25% of the Rayleigh length range (488nm) and 30% of the Rayleigh range (532)

If the customer provides their own power supply, the DC power supply must meet the following requirements: power>60W, ripple<5% peak to peak, and power adjustment rate<0.5%

5. Use original special heat sinks or other heat sinks with sufficient heat dissipation.
