High resolution laser head is called HR head for short. Its special structure makes the laser beam be focused into a smaller focal spot than the standard laser head, which makes the engraving result more delicate and exquisite. So the HR head is more suitable for engraving high precision photos and also a good performance on 3D engraving. Besides, because of the very small laser dot with high energy density, the HR head can be even used to engrave some metals directly!
