For biomedical applications, laser micromachining of glass is in high demand – particularly to create lab-on-a-chip or microfluidic chips. One of the biggest challenges when making lab-on-a-chip is to machine the high-precision pipes, vessels, and valves inside the glass chip.
Micromachining of very small features in glass is difficult due to its brittleness and transparency. With conventional tools, it is practically impossible. However, ultrafast lasers can do the job. When the pulse duration is below some tens of picoseconds, the laser-material interaction enters the cold ablation regime and the machining quality and precision become very high.
We have successfully machined typically sought lab-on-chip features and marking on glass with our Onefive ORIGAMI XP femtosecond laser.
The ORIGAMI XP has been designed for easy and cost-effective integration. It comes in an air-cooled, single-box chassis with removable handles and offers full remote-control capabilities. With a rugged design and low maintenance costs, it is ideal for many industrial applications.
