As we know, the normal configuration of a fiber marker engraver is 20W power with 110 x 110 mm lens.

Usually, the marking engraving within 110 x 110 mm area is enough for most kinds of laser marking engraving application needs.

But a few customers need to engraving marking some bigger patterns or logos sizes than 175 x 175 mm or 200 x 200 mm, even 300 x 300 mm. Then what configuration should be equipped to fulfill the needs and best accurate marking engraving demands?

If the marking area 175 x 175 mm or 200 x 200 mm, the wattage of the fiber laser source must be at least 30W. If we use the 20W for 175 x 175 mm, of course, the machine also could mark engrave on the subject, but the edge may not be marked or engraved well, as the laser has week function on the edge of the 175 x 175 mm area.

So the lens’s size is not the larger the better, we should consider the relevant wattage of the fiber laser source’s power equipped.

According to the practical situation, we can give some configuration formula suggestion as below:

Fiber Laser Marker Engraver 10W:  Laser Processing Area|(f-theta lens chosen): 70 x 70 mm

Fiber Laser Marker Engraver 20W:  Laser Processing Area|(f-theta lens chosen): 110 x 110 mm

Fiber Laser Marker Engraver 30W:  Laser Processing Area|(f-theta lens chosen): 175 x 175 mm or 200 x 200 mm

Fiber Laser Marker Engraver 50W: Laser Processing Area|(f-theta lens chosen): 200 x 200 mm or 300 x 300 mm

Fiber Laser Marker Engraver 100W: Laser Processing Area|(f-theta lens chosen): 300 x 300 mm
