Hi all,
I'm looking for a couple of ZnSe lenses for my 60watt co2 laser.
My machine (lg1200) is equipped with the standard 20mm, FL= 2 inch lens, and is performing quite well with it.
I hope that with a FL=1 inch lens it will be possible to engrave in more detail.
and with a FL=3 or 4 inch it would cut better in thick materials like acrylic 12mm and mdf 12mm
Is there really a big difference in performance between the different focal length's in the area of engraving and cutting?
Or are the differences minimal?
Also i'm looking for a good shop where i can buy these lenses at a fair price
On ebay for example you find lenses from about 50 USD up to 200USD each.
Does the quality of the engraving/cutting really depend on the quality/price of these lenses, or is it more something of the time the lenses will keep doing there job before they are defective?
Best regards,
Ferry.......
