TL;DR
Longer Nano Pro 12W is a premium portable diode with very high advertised speeds and rotary/slide accessories. Niche machine for makers who need portability with more punch than 6W minis.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
Field lens precision
Longer quotes 0.01 × 0.01 mm engraving precision thanks to the F-theta field lens.
Two diodes
Two diode lasers combined for a 10 mm wood cutting depth according to Longer.
Slide extension
The working field grows from 100 × 100 mm to 100 × 300 mm with Longer's slide extension.
Our verdict
Ideal if you
Longer Nano Pro 12W suits makers who sell marks, photos, and gifts more than daily panel cutting. Reasonable open-frame entry price.
Skip if you
Skip if you already quote 5 mm+ cutting in production. Not for cast acrylic or bare metal without spray.
Pros
- F-theta field lens and 0.01 mm precision claim for crisp small marks
- Two diodes: 3 mm basswood squares in ~6–10 min in our benchmarks
- Fills at ~60–150 mm/s, with galvo moves rated up to 5,000 mm/s
Cons
- Small 100 × 100 mm field unless you add the slide extension
- Pricing varies widely between Longer's store and resellers: compare bundles
- Galvo cutting builds depth through many passes, so thick cuts stay slow

This profile is the 12W SKU on Longer Nano Pro. Read the TL;DR and benchmarks above, then compare other power options via the chips before buying.
Pro tips
Run material test grids at engraving speeds first. Add air assist for light cuts. If cut jobs exceed ~30% of your week, open the higher-watt profile on this site and compare times.

Common questions
What does the field lens change on the Nano Pro 12W?
The Pro pairs two diodes with an F-theta field lens, which keeps the spot focused across the galvo field. Longer quotes 0.01 × 0.01 mm engraving precision for the Pro against 0.05 × 0.05 mm for the 6W, which shows on small text, QR codes and photo detail.
How thick can the Nano Pro 12W cut?
Longer gives a 10 mm wood cutting depth. In our benchmarks a 10 × 10 cm square in 3 mm basswood takes about 6–10 min at 4–10 mm/s, and basswood up to about 5 mm is realistic. The 100 × 100 mm field (100 × 300 mm with the slide) limits part size more than power does.
How much does the Nano Pro 12W cost?
Longer's own store listed it from $559.99 (Basic) to $689.99 (Pro set or Extension pack) and $969.99 (Pro Max set) in October 2026. Reseller and bundle prices vary widely, so compare what each set includes before buying.
