The premium quality 2 1/2" focal length lens for Trotec Speedy machines is a good, multi-purpose engraving and cutting lens.  It provides good quality engraving over very large areas, with minimal change in engraving dot sizes.  In other words, the variation in height fluctuations of materials and the machine's table, over larger areas is offset by using this lens.  The same is true for cutting as well.  And, certainly it can be used for any size job whether small or large.

LaserUser.com author/publisher Gareth Lewis said, "[Regarding the] Cutting Lens...The best solution for this lens is a 63.5mm GaAs Plano Convex Flat DOWN. The reason for using this lens is that based on the Data from the “Cutting Performance of Different Lenses at their Measured Depth Intensity Focal Point” table, this is the best cutting performance available. In addition, it focuses at the manufacturers specified focal position of 63.5mm
