Same laser.
Better process.
The laser beam shape decides how your process performs: quality, speed, stability. Midel engineers all-reflective optics, including unique 3D beam shapers, for machine builders, system integrators and end users. We stay with you from the first optic to volume rollout.
Selected customers and partners who trust us
As laser power moves into the background, the beam shape moves to the front.
For machine builders, system integrators and end users, the beam shape is where systems now set themselves apart: quality, scrap rate, throughput. Midel is a beam-shaping specialist. We design the shape, take you from first project to qualified series part, and help you build laser systems that meet rising end-user demands. Our mission: give every laser system exactly the beam shape it needs.

3D Beam Shaping
Midel uniqueIn production, what counts is process stability, part after part. A conventional beam keeps its shape only right at focus, over a very short range, which is why we engineer it along the propagation axis instead. The result: an extended depth of focus that turns a focus-critical step into a forgiving one.
3D Gaussian
Real parts are never perfectly flat, and lasers drift under thermal load. This shape turns the Gaussian’s knife-edge waist into a long working band, so the part can sit where it actually sits, with no focus tracking required.
- Up to 5× the depth of focus
- Keeps a near-diffraction-limited spot
- Holds up in multi-kW setups where transmissive optics drift
3D Top-Hat
The first flat-top engineered for depth rather than for the focal plane. Every conventional shaper builds a clean plateau in one thin slice and lets it decay into a peak on either side. This one holds it, so the flat-top is still flat where your part is.
- ~5× the stable range of a conventional shaper
- As small as physics allows — only 1.5–1.8× the Gaussian spot size
- Superior performance proven across a range of applications
3D Ring-Core
Wraps a laser spot in a ring and holds that geometry across virtually the full depth of focus, whereas a dual-mode laser’s ring collapses within a fraction of the Rayleigh length. A calm keyhole, less spatter, clean at higher feed rates.
- Ring + core stable through the focus
- Independently verified by Primes on single- and multi-mode systems
- Ring-core behaviour without a ring-core laser
3D Custom
When none of the profiles above is the right answer, we design the distribution around your process instead. We always appreciate a challenge to the limits of physics.
- Intensity profile designed to your process
- Depth stability engineered in from the start
- Same passive, all-reflective single-mirror build

Multispot optics for parallel, high-throughput processing.
What a better beam profile is worth
The value of our beam shapers shows up as numbers our customers can measure: a wider process window, less scrap, higher throughput. Browse use cases we can share to learn more.
A focus-critical step became production-ready
A homogenized flat-top stays on-size across a 4–6 mm focus range, where a conventional shaper held about 2 mm.
Ring-core performance without a ring-core laser
A single-mirror retrofit brought spatter-free seams and a wider process window to an existing welding laser.
Focus tracking became unnecessary
Ablation depth held to ±2% with a constant wall angle, turning a closed-loop step into a simple open-loop process.
From first prototype to series production, we guide you every step of the way.
Beam shaping gets complex quickly, and you don’t need to become an expert in it. That’s our job. And it all comes down to one thing: a process ready for series production. We’re there for the first designs, for integration, and for proving what the beam is worth in your process. The first optic is usually in your hands within three weeks.
Reflective optics, built to integrate
Our beam shapers are all-reflective, micro-structured mirrors: strong, power-tolerant, and tuned to your laser, setup, and application. Our own optimization methods shape the beam in three dimensions, along the axis it travels, not just in a single plane. Integration is usually as simple as swapping a mirror.
Two things set us apart, and they work together:
Unique manufacturing
A continuous, micro-structured mirror surface, produced in-house, power-tolerant and patent-protected. Not an etched, off-the-shelf DOE.
Innovative computing methods
We compute across the full beam volume, not just one plane, and design against your laser’s real M². That’s what makes stable 3D and EDOF shapes possible.
Why integrators build us in
A component change, not a machine change
The energy distribution decides what the process can do. Reaching it costs you one optic in the beam path: not a bigger laser, a new source or a redesigned head.
Built to survive your customer's floor
You sell machines, not experiments. What we deliver has to hold its beam shape through three shifts a day, 24/7, with nobody watching. That means holding it across the wavelengths, pulse regimes and beam qualities your customers run.
DUV–NIR · CW–fs · SM & MM · W to multi-kWDesigned once, then repeatable
We manufacture and qualify every beam shaper in-house, from the first prototype to the 1,000th series part. Performance stays consistent and within the defined specification.
