Full Spectrum 1.5" Focal Lens
|If your laser engravings require extra fine detail, such as for engraving font sizes smaller than 8 points, we recommend this shorter 1.5´´ lens. Shorter focal length lenses have a smaller minimum spot size, but spread out more quickly on either side of the focal point. This makes them better for fine detail but not ideal for thick cutting. Longer lenses—such as the 2´´ lens that comes pre-installed on the H-Series Lasers—are ´´in focus´´ for a greater portion of the beam length. This allows for straighter edges during cutting, but the minimum focus point is not as small.
