Whats the difference between lenses size in a fiber laser engraving machine?

[@mr1enrollment]

The longer lens for greater area also means the spot size of the laser beam is larger. Therefore the same energy in a larger spot means slower cutting.

I doubt that the alluminium sheets used are 0.02mm. Looks more like 0.2mm

Please make videos of chaging laser source, changing galvanometer

Does this apply to the same later that I just purchased? Galvo Compact 20 - 20W Integrated Fiber Laser Marker Engraving Machine with 4.3''x 4.3'' Working Area for Metal

[@BigPoppaR]

Great information. So you would say that using the smallest lens that your project will fit within the footprint of is good practice?

[@REKKnives]

What is the optimal engraving area for a 60w?

[@jguadiz]

How big of an area can a 150mm lens cover? I've heard it can cover a larger portion than 150mm. Thank you

[@aishamysticjeweler5544]

Greetings, do you have any video to change a 100mm lens to F-Theta 150mm please and Thank You ?

[@CraftyHomeChic]

Hello, maybe my question will sound very silly... how do I know what size my lens is?

[@DjBillyT]

What's the difference in parameters with each lens So if was using a 110 lens and changed to a 175 What increases and decreases would be needed in the engraving parameters

[@maxtipex]

Can you buy different lenses and use the best one based on the work you have to do ?

[@tobiashangler8266]

yes you can with all models i know

[@coulterjb22]

Do you have anything with depth of field per lens? (I'm wanting to engrave uneven surfaces without using a 3D head)

[@eduardo.e.a]

Hello, what happens if you use a 100x100mm lens on a 100W laser?

[@KinoTechUSA69]

You get some serious power, that's what lol

[@AbdulAzeez-qy3di]

This Is Very Nice.

[@coulterjb22]

I hope their customer support has a better response time than their videos lol

Houw much nepali praise ?

[@clfung2008]

This should be a 0.2mm Aluminium plate , not a 0.02 plate you are using !

[@rush2crush470]

thankyou

[@mysafename1694]

Thank you for doing a good job, but please get rid of the music in the background. It's a little distracting. Do you have anything more recent? Thank you.
