For transparent materials like glass micromachining, WOP uses Selective Laser-induced Etching (SLE). This technology is suitable for micro parts, channels, and diverse cuts in transparent materials fabrication.
Our used SLE technology allows us to reach exceptional properties on transparent materials.
Selective laser etching is a two-step process.
In the first step, we modify glass by using ultra-short pulse laser radiation. Ultra-short pulses can effectively make modifications inside the transparent materials, and only one pulse is enough to go through the substrate. It ensures speed and quality for volume production.
In the second step, we remove the modified areas by using wet chemical etching. Selective (SLE) means that modified areas are affected by etching a lot faster than unmodified, making it possible to achieve the desired result.
We have optimized the process that allows achieving sufficient accuracy with speed suitable for the industry.
