VDO SERIES DOME LIGHT
■ User-friendly dome lighting with high radiance and high uniformity. ■ Ideal for canceling irregularities and printing inspections. ■ Available in multiple wavelength and full color models.
What is Dome Light? Semi-spherical shaped lighting. Installed close to the workpiece.
As light is emitted from a wide range of angles, it is suitable for inspect- ing pattern irregularities, printed characters and dusts without making shadows of uneven surfaces stand out.
