Diamond protective windows
Coating-free.Laser windows.
For CO₂ and fiber lasers, cut to fit your cutting head.
We pattern the anti-reflective surface directly into diamond, so there’s no coating to burn off when spatter hits.

The problem
Replacing windows
stops production.
Spatter, smoke and residue collect on the protective window. They absorb laser energy and heat the coating until it fails. Replacing the window means stopping the machine.
We’re developing diamond windows to reduce those replacements and the downtime that comes with them.

How it works
We pattern the
diamond itself.
Our process forms anti-reflective structures directly in the diamond surface. No separate film is needed.
Structures in diamond
Tapered features are formed in the diamond surface itself. There’s no separate coating to burn off or delaminate.
No coating to burn off
Anti-reflective geometry built directly into the material.
Spreads heat
Diamond’s high thermal conductivity helps spread local heat.
Cut to fit
Custom dimensions for your existing laser and cutting head.
Why diamond
Diamond handles heat.
Diamond combines high thermal conductivity with a hard surface and broad optical transmission. Those properties make it useful for laser windows.
- Thermal
High thermal conductivity
High thermal conductivity spreads heat away from local hot spots.
- Mechanical
Hard surface
Diamond’s hardness helps it resist surface damage.
- Optical
Broad transmission
Diamond transmits across a broad spectrum, from UV to far infrared.

Applications
Where these windows are used.
We’re starting with industrial laser processes where spatter and contamination cause frequent window replacements.
Metal cutting
High-power cutting with metal spatter.
Laser cladding
Exposure to powder, spatter, and heat.
CO₂ processing
Materials processing with CO₂ lasers.
Application illustrations, not customer installations. Material suitability is reviewed for each laser.
Pilot program
Test a window
in your machine.
Test a Zeflect window alongside your current window. Track how often you replace each one and how much downtime each replacement causes.

After protective windows
Other optics, the same process.
We’re starting with protective windows. Longer term, we plan to apply the same patterning process to other laser optics and photonic components.
