OMTech product photographTwo 60W MOPA machines. Different focus routines, marking fields and packages.
Both are 60W MOPA engravers. One focuses automatically; the other offers a larger marking field. The better fit depends on the size of your designs and how often you change the height of the parts beneath the laser.
Researched buyer guide · Checked October 19, 2026
We have not tested these machines ourselves.
OMTech’s 60W MOPA Autofocus lists a 150 × 150 mm marking field and automatic focus. The 60W MOPA Split has a larger 175 × 175 mm field and manual focus. Both offer pulse control; LightBurn licenses and accessories depend on the package. We have not tested either machine; this comparison uses published specifications.
01 / Autofocus versus Split
The Autofocus model lists a 150 × 150mm field; Split lists 175 × 175mm. That is the area the laser can mark through the supplied lens, not the size of the plate holding your work. Compare it with your largest design before choosing.
Two 60W MOPA models
OMTech product photographs over an illustrated metal landscape. The metal finishes are not test samples from these machines.
We would shortlist Autofocus for a mix of parts with different heights, provided your designs fit its 150 × 150mm field.
The mounting plate is larger than the marking area. We have not measured how much time autofocus saves.
We would shortlist Split for larger designs or repeated batches where manual focus is manageable. Its listed field is 175 × 175mm.
OMTech names a JPT source for this model. We could not confirm the source brand in the Autofocus model.
Both machines are rated 60W. That does not make their lenses, focus controls or packages interchangeable. Check your largest design against the supplied field, then confirm the controller, LightBurn license and rotary support before ordering.

OMTech lists Autofocus as Class 4. We could not confirm Split’s classification from the documents checked; do not assume that makes it safer. Obtain the safety and enclosure requirements for whichever model you buy.
02 / Laser terminology
These terms describe different parts of an engraver. “MOPA” tells you about the laser, “galvo” describes how the beam moves, and “split” describes the machine’s layout. A machine can be all three.
The feature that distinguishes MOPA
Compared with a conventional Q-switched fiber laser, MOPA gives you control over pulse duration as well as frequency and power. Colored metal marks still need suitable material and settings to get the result.
OMTech’s explanation of MOPA and conventional Q-switched fiber
Beam movement
Mirrors steer the beam across the marking field. Both ordinary fiber and MOPA lasers can use galvo scanning; the word does not imply autofocus.
Part height
Useful when you switch between parts of different heights. Repeated batches in one fixture may suit manual focus. We have not timed the difference.
Bench layout
The source/control box sits beside the marking stand. Allow bench space for both and check the connecting cable’s reach.
03 / Software and setup
Both listings mention LightBurn, but both also sell a separate “Machine with LightBurn” package. If you want to use it, check whether you already hold the right license or need to include one in the order.
License tier
A compatibility claim does not include a license. Both models have a separate “Machine with LightBurn” package.

04 / Packages and prices
These were OMTech’s US package prices on October 19, 2026. Tax, freight and final checkout totals are unconfirmed. The rotary, LightBurn and extractor options are separate packages; choosing one does not mean the other extras come with it.
Machine package
150 × 150 mm field with automatic focus. LightBurn, rotary and extractor are separate named options.
Machine package
175 × 175 mm field with manual focus. LightBurn, rotary and extractor are separate named options.

Confirm the full contents of the package you choose. The 70/80mm rotary names are OMTech’s accessory descriptions, not a guarantee that your object will fit. Prices above come from the Autofocus product data and Split product data.
OMTech’s product data marked these packages available. We have not verified warehouse stock or dispatch, so confirm timing before accepting customer work that depends on the machine arriving.
05 / Before ordering
A sample on your own material is the best way to judge whether the finish suits your work. Then check the physical setup, software and accessories below so the delivered machine can do the jobs you bought it for.
Check 1
Use your alloy, coating, finish and artwork. Compare contrast or depth, and find out how long the full job takes, including loading and handling.
Check 2
Confirm the supplied lens, marking field and height clearance with your fixture or rotary fitted. Your object must fit physically and your design must fit the laser’s usable area.
Check 3
Get the controller details, configuration and lens-correction files, and instructions for your operating system. Confirm the focus and rotary functions you need.
Check 4
Have OMTech list the license, rotary, extractor, fixtures and lenses included in your package. Price any missing items before comparing totals.
Check 5
Obtain the model’s safety classification, enclosure and extraction requirements, electrical requirements and training information. Autofocus is listed as Class 4; Split’s classification remains unconfirmed here.
Check 6
Confirm delivery arrangements, return freight and who provides service. Check the laser-source warranty separately from the rest of the machine.
We would not buy either as a general sheet-metal cutter or welding machine. A demonstration cutting a thin piece of metal does not show that it will make production parts with the edge quality and speed you need.
For fiber engraving with a diode for other materials, compare Solis Duo. For wood and acrylic sheet cutting, see our OMTech CO₂ comparison. If you also need thin-sheet metal cutting, read the MCore guide.
Compare current offers
Our shortlist would favor Autofocus for frequent changes in part height, and Split when the larger field fits a design the smaller one cannot. These are recommendations based on specifications, not a tested speed or quality ranking.

No. We researched OMTech’s listings and LightBurn’s documentation, checked October 19, 2026. We have not tested these machines or compared their engraving quality, focus accuracy or speed.
MOPA describes a fiber laser with adjustable pulse duration. Galvo describes the system steering the beam. Autofocus adjusts focus automatically, while split means the source/control box sits separately from the marking stand. A machine can be MOPA, galvo and split at the same time.
Autofocus lists a 150 × 150 mm field and automatic focus. Split lists a 175 × 175 mm field, manual focus and a JPT source. Both publish 2–500 ns pulse width and 1–4000 kHz frequency. The practical choice is between automatic focus and a larger listed marking area; we have not tested their results side by side.
No license should be assumed from a compatibility claim. Both models checked here have a Machine option and a separate Machine with LightBurn option. LightBurn lists EZCad2 galvo support under Pro. Confirm your machine’s controller, required tier and included license with OMTech.
The listings name those as separate packages. Do not assume a rotary or extractor option also includes a LightBurn license. Get the complete contents in writing, including the lens and any fixtures you need.
We could not confirm that it applies. The manual linked from the 60W Autofocus page is titled LYF-20/30/50W, revision UM-FMM-0061-V4. Obtain the matching 60W manual and configuration files from OMTech before setup.
No. Colored marks depend on the material, finish and laser settings, so compare a sample on the metal you use. These two machines are primarily marking and engraving options in this guide. We would not treat a thin-metal cutting demonstration as proof that either can replace a production sheet cutter.
OMTech’s US product data marked all nine packages available on October 19, 2026. We have not confirmed warehouse stock or shipping dates. Check those, along with freight and tax, before placing an order.
