Co2 Laser (10.6um) Beam Combiners

Beam Comnbiner Lens 20mm

Needed to replace to supplied lens in my Yhongli Red Dot Combiner. I first tested power at 50% power to have a bench mark before installing the red dot unit. With a 130watt tube,@ 19ma it was outputting about 68watts... After I installed the Yhongli red dot beam combiner, which screws directly on the end of the Yhongli Tube easy install, I did the same power test again.... it measured around 45watts.... not good.... So I set the beam combiner aside....very dissapointed.... I had used APC products and know them to be high quality so I ordered the 20mm lens only to replace the Yhongli units lens.. Today did the same testing and was happy to see NO loss of power... I did the test 3 times to be sure and all times they matched the bench mark results... To say the least I was happy to get the hanging red dot off the Lens tube and allow me to swap out lens with ease.... Again Steve's products have proven to high quality... I will always come back to APC for my lenses and mirrors...... Thanks to Steve and Lou for great products and support.... Chuck

All smooth!

I probably should have ordered two. Great service and no hassles.
