Crystal Photo Pendant

On the base plate, first place a frosted black aluminum sheet. This facilitates focusing the laser on both the frosted aluminum surface and the contacting glass surface, while enabling precise engraving of patterns onto both the aluminum sheet and the crystal base.

Note: After the focus adjustment is complete, the machine can be raised by 0.5 to 1 mm. This adjustment reduces the laser energy acting on the frosted aluminum sheet, preventing excessive removal of the underlying coating that could cause uneven patterns.

Subsequently, cleaning the surface ash with water will yield a uniform and finely detailed engraved design.
