The difference between CO2 reci laser tube and RF laser tube for laser marking machine

2019-11-01 12:20

For CO2 laser marking machine, some people don't know how to choose laser tube. there are have two kinds of laser tube-Reci laser tube and RF laser tube.Now i'd like to tell you the difference.

 

 

 

1.The spot effect is different
The metal RF tube exit spot pattern is close to: TEM00.When we adjust, we can see that the spot of CO2 metal RF tube is very small.
It can be seen after finish that the spot is round and uniform, and the general radius is between 1-2mm. Of course, depending on the laser power,The size of the spot varies, depending on the actual situation.

The spot pattern of the CO2 glass tube is different from that of the RF tube, and the TEM00 mode light cannot be seen.
The divergence angle is also relatively large, and the angle of divergence is relatively large, and the divergence angle that can be compressed is limited,resulting in a large focusing spot of the marking machine, so the marking effect is poor.

2, different service life and stability
The laser stability of the CO2 RF tube is good, it can be reused without insufflation, and it can be reused without replacement.
The use time of RF tubes is generally more than three years. Some imported RF tubes can even reach more than seven years(Ameirica Synrad),and the service life is much longer than that of glass tubes.

The stability of the CO2 glass tube is relatively poor, and the use time is relatively short. The brand warranty is different for different brands.
The service life of the laser tube is more than 10 months. The glass tube can not be reused. When the laser attenuation is very strong, it indicatesthat the glass tube needs to be replaced. Generally, the glass tube is used for half a year to one year.
