A "Must" K40/3020 upgrade.

Review by Bob on 3/22/2017

It makes a considerable difference in results from the stock cheap Chinese laser lens. Together with the laser head/air assist (http://www.lightobject.com/18mm-Laser-Head-wAir-Assist-Ideal-for-K40-Machine-P701.aspx). Just remember the lens is situated slightly higher up than the stock laser head. I found the sweet spot was about 0.90" from tip.

Hugh performance increase. I highly recommend. I bought this lens in combination with a 20 mm Gold plated mirror.

Sharp focus, faster cuts!

High quality lens! Great support

Review by Stuart on 10/15/2018

Great support from Light Object. This was a drop-in replacement for my 4040 Chinese laser, but I think the optics are better.

Way better than stock

Much better than the stock K40 lens. Sharper focus and better cuts
