LU2-2 Fixed Focus Laser Module
It has a smaller Luminous Cavity, so it`s lower power but high cost-effective, also has a smaller Focal Spot.
Optical Power: 1,000-1,600mW
Voltage: 5-6V
Electric Current: 1.1-1.35A
Wavelength: 445±10NM
TIPS:
1. LU2-2 is good at engraving high-precision pattern, but speed couldn`t be set too high.
2. It`s not good at cutting.
3. 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.
4. The competitors may falsely promote the power of similar laser modules as 10W or even 20W, please take care.
LU2-4-LF Optically Compressed Laser Module
With Air Assist Nozzle to ensure very clean cutting edge
Optical Power: 4,500-5,500mW
Voltage: 4.2-5.0V
Electric Current: 3.4-3.6A
Wavelength: 445±10NM
TIPS:
1. LU2-4-LF is good at engraving and better at cutting, and could support a higher speed.
2. It has the air assist, but you need to buy a Air Compressor to support the air assist.
3. 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.
4. The competitors may falsely promote the power of similar laser modules as 40W or even 60W, please take care.
LU2-4-SF Optically Compressed Laser Module
Better for Engraving
Optical Power: 4,500-5,500mW
Voltage: 4.2-5.0V
Electric Current: 3.6-3.8A
Wavelength: 445±10NM
TIPS:
1. LU2-4-LF 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.
