Sapphire Drilling

We offer sapphire laser drilling services.

Sapphire drilling using femtosecond laser radiation is a unique processing technique enabling no cracks in hole peripheries, accurate taper control, and smooth wall finish.

We have extensive knowledge of processing for a variety of brittle materials, including sapphire and ruby.

As one of the hardest materials, sapphire is a widespread choice for companies that work with reliable and durable high-tech products.

We continue the development of sapphire drilling techniques to meet our customers’ needs.
