OMTech F Theta Lens for Fiber Laser Engravers, 110x110mm Replacement Optical Scanning Lens for 1064nm Fiber Cutter Marking Engraving Machines, Laser Etching Accessory Field Lens Upgrade, M85x1 Thread

Has the smaller tower and as is 60 watt with a larger field in order to use rotary you need more height Without a doubt this is a great package 60 watt fiber

Overall the laser works fine with Lightburn software. I question the actual power? I also have a Mecco 20w fiber laser that I can compare this too. I would say the Mecco is 5 times faster at doing the same work. I cannot achieve the dark mark on bare aluminum that I can with a Mecco. This one will mark color which my Mecco will not do. Price....you get what you pay for as this is about 5 times cheaper than my Mecco. I would say this is OK for prototype or small batch work. Not recommended for high volume runs.

it works, lot stronger laser vs the 175x175

These guys are great at reaching out When I had an issue that was quite frustrating. The memory stick may be identified by windows as having viruses. To get around this, download your own copy of Lightburn, and do not use the enclosed software. Watch a video on YouTube will show you how to install the set up files and configuration files that you will need to go between your laser and Lightbourn.

This is my 3rd lens from omtech. The other 2 were packaged very well. This one very little packing in the box.
