Laser Engraving

Fig.1:Examples for laser engravings

LAYERTEC uses laser engraving as a standard for all substrates and optics made of Fused Silica. It is possible to mark the edge as well as coated or uncoated functional surfaces.

The minimum character height is approximately 1.5 mm. Usually the optics are engraved on the edge (surfaces).

In direct contact with our sales department, please clarify for which materials and geometries such engraving is useful or necessary.
