The premium Gallium Arsenide lens with square holder for Trotec Speedy 500 machines is typically used to achieve a longer vertical cut.  And, for cutting thicker materials.  However, this comes at a price--that being slower cutting speed caused by the larger size of the laser beam.  But, the key benefit of this new technology and orientation is that much less laser power is required to cut, as compared to the four inch focal length lens.  Again, the key is that the four inch lens requires four times the laser power to achieve a similar speed as the two inch focal length lens. But this new technology lens requires double the power to do the job at roughly the same speed as the two inch focal length lens. This new technology is recommended for Speedy 500 customers that have medium thick materials that need to be cut with a vertical wall, or even thin materials that need a straighter edge, and do it with higher production throughput.

​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
