  • EXACTING LENS DIMENSIONS: Each lens is engineered and built with only a 0.003mm margin for error to ensure finer laser focus on high-resolution engravings and enable sharper cutting abilities.
  • ULTRA-PURE MANUFACTURING: American Photonics utilizes an ultra-clean production room to ensure every focal lens is free from all impurities, reducing heat damage and ensuring extremely consistent laser beam transmission.
  • HANDMADE IN THE USA: Each American Photonics focal lens is cored, polished, edged, coated, and packaged by hand with expert precision in each step.
  • EXTREME HEAT TOLERANCE: Crafted to resist heat damage, cracking, and staining. A melting point of 2777°F (1525°C) easily withstands the thermal demands of CO2 laser applications.
  • SUPERIOR LIGHT TRANSMITTANCE: Both sides are carefully coated with a strongly anti-reflective finish optimized for infrared light at a wavelength of 10.6 microns.
  • LASTING DURABILITY: Our laser engraver focus lenses' double-sided coating process ensures outstanding scratch resistance for longer service life.
  • WIDE COMPATIBILITY: This laser focus lens is designed to work with all CO2 laser engravers below 200W. Please check the focal lens diameter in your machine’s manual before purchasing.

    Summary:

    As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.

    How to Select the Proper Focal Length:

    A lens with a shorter focal length (1.5"–2.5")  has a smaller focal point to provide sharper details for high-resolution images. A longer focal length (usually up to 4") has a larger focal point and extended depth of focus (or focus tolerance) which is better suited for cutting applications. Also, keep in mind that using longer focal lengths subtract from your workbed’s Z-depth.

    Excellent value for an automatic watch, keeps VERY good time.
    Color: Grey, Color: Grey
    I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

    It looks really cool and striking.

    Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

    A Beautiful Timepiece at an Awesome Price!!
    Color: Grey, Color: Grey
    I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

    Classy and sporty. Great value!
    Color: Grey, Color: Grey
    Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

    Stunning Gentleman's Watch
    Color: Grey
    This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.
