The medium quality 1 1/2" focal length lens for Trotec machines is commonly used for high resolution engraving, as well as printing small fonts and very fine detailed works.  In comparison to the most commonly used lens, the two inch lens, the 1 1/2" lens is about 40% smaller in size.  Another use is for cutting very thin materials, less than a sixteenth of an inch.  The concentrated power of the smaller spot size (increased energy density) enables cutting of very thin metals, when paired with the smaller orifice nozzle.  Note, that the 1 1/2" lens is not widely used for engraving because the focus range is very sensitive, and thus a slight change in height will significantly change the spot size. So, as materials and laser tables are subject to height variations, especially when the surface for engraving is larger, the applications for the 1 1/2" lens tend to be dimensionally smaller works.
