Visible Light Shielding Ceramics

This is our unique white ceramics that shields visible light including laser light.

– It is alumina-based white ceramics with excellent heat resistance,
   wear resistance, and chemical resistance.

– Light in the visible light wavelength range is reflected by the surface layer
   only to prevent transmission and internal scattering.

– When the laser beam of 1mW or less like a laser pointer is irradiated,
   the penetration depth of the irradiation light is suppressed
   within a few micrometers from the surface.

– Its light density of 4.6 g/cm3 and corrosion resistance
   make it easier to handle than metal materials.

Application: Ceramic component for calibration of 3D scanners

Using visible light shielding ceramics,
the laser-based measurement of 3D scanners can capture areas
closer to the outermost surface than existing ceramics.
Therefore, it is suitable for calibration of 3D scanners.
