LU2-4-SF Optically Compressed Laser Module:
It has a shorter Focal Length, so it has a smaller Focal Spot, but shorter Depth of Field.
Optical Power: 4,500-5,500mW
Voltage: 4.2-5.0V
Electric Current: 3.6-3.8A
Wavelength: 445±10NM
Focal Spot: About 0.08 x 0. MM

FEATURE TIPS: 
1. LU2-4-SF is good at cutting and better at engraving harder materials (such as stainless steel and other hard materials), and could support a higher speed..
2. It is not that the smaller the light spot, the better the effect. When engraving photos, you may need to increase the laser spot to get a better picture effect.
3. The competitors may falsely promote the power of similar laser modules as 40W or even 60W, please take care.
