Mahr Federal has introduced a new addition to their growing family of optical shaft measurement systems. Competitively priced and designed to provide fast, accurate, fully automatic measurement of smaller shafts and turned parts directly on the shop floor, the MarShaft SCOPE 250 plus features a highly accurate matrix camera with four million pixels. The system measures parts up to 250 mm in length and 40 mm in diameter with an accuracy that is previously unknown in this market segment. An MPE (Maximum Permissible Error) of less than 1.5 microns + L/40 when measuring diameter and an even more impressive 3 microns + L/125 when measuring length is significantly more accurate than other systems using line cameras.

One key to the system’s speed is the state-of-the-art, high-resolution CMOS matrix camera with a live image field of view of 40 x 24 mm, enabling it to capture an entire part diameter in a single view. With Z-axis positioning speeds of up to 200 mm/second and an image acquisition rate of over 120 images per second, measurements are performed faster than the blink of an eye. Zoom functions allow measurement of the smallest details such as chamfers and radii, which can be difficult and in some cases even impossible to test, with conventional measuring methods.
