PRESIONQI 20mm CO2 Laser Spiegel Si Reflecterende Mirrors Verguld Silicium 3PCS CO2 Laser Lens,voor CO2 Laser Graveren/Snijmachine 40W-400W

These Si coated mirrors arrive in a branded cardboard box with each of the individual mirrors placed into their own sealed Mylar pouches with a quick-tear section on the top. Each piece was also wrapped with a protective soft covering to keep it from moving around or taking any damage from the bag itself. After unpacking and inspecting them, all of them were flawless with no blemishes or marking present. The back of each is etched with the lens surface material (Silicone Mirror), the diameter (25mm) and the thickness (3mm) so they’re easy to identify.If you’re looking to upgrade mirrors for a pre-built machine’s stock setup, keep in mind that these may not necessarily be the same size or thickness and may need modified mirror holders to drop into place. The machine I've been designing and working on is very much a mishmash of 3D printed parts, flat sheet metal and extrusions where necessary, so I only had to tweak a few things to accommodate these instead of the K40 style mirrors I'd been using before.Realistically there isn’t much of a notable difference in real use and the main thing is going to be how long they last with proper air assist, exhaust and a sensible schedule for cleaning, though that’s not really something I can actually test in the month I've owned these. They’ve been doing the job well after calibrating the alignment and giving the machine a few tests with them in place alongside the focusing lens I also received from PRESIONQI. Though it’s very much unfinished overall, so I haven’t got everything fully buttoned up to really put them through their paces yet.Overall, first impressions are good, but I really can’t comment on more intensive and extended use just yet. I'll be sure to update the review if anything comes up that can be attributed to the mirrors or focusing lenses from this company, but honestly they look as good as any other mirror set I've used in & slightly above this price range.Honestly they look completely identical to any other budget C02 mirror you can find on Amazon from a bunch of different brands, the only actual difference is the name on the sticker applied to the box. The £27.99 price is also a little cheaper than other vendors selling the exact same spec mirrors on Amazon, so if you need them on short notice this is one of the better options at the time of writing.

Very good quality refraction lenses. Fit perfectly on my GWeike 130w co2 laser. Very good quality and changing my lenses definitely made a difference as the old ones have been in since new.Seems easier to align now as well.Good value and happy to recommend!

This is a set of three standard 1-inch silicon reflective lenses for CO2 lasers.As you might expect for the money these are not particularly high-spec, but they are fine for more normal users and setups.They come in generic packaging that protects them well, so no complaints on that font.The product description has all the bases covered, so these seem to be a decent buy if they are what you’re after.OVerall impressive for the price, especially considering the ‘pro’ competition that costs far more.

Replaced my ageing CO2 laser mirrors as they started to age and these are better than the original. The beam is significantly stronger and cuts with ease. A great replacement and something I wish I hadn't overlooked for so long. Really pleased.

This 25mm reflection mirror is a game-changer for my CO2 engraving and cutting machine! It delivers fantastic reflection, ensuring sharp and precise results for everything from delicate engravings to clean cuts.The multi-way design adds great versatility, making each project smoother and more efficient. It feels like having a little assistant that takes care of every detail. For anyone passionate about laser engraving, this mirror is a must-have to take your work to the next level!
