Universal length measuring instruments with laser measuring system are mounted on highly homogeneous rigid granite in a horizontal configuration
X-axis measuring system: interferential laser measuring system, 525 or 1115 mm long
Z-axis measuring system: Renishaw incremental, precision length measuring system, 80 mm long

High end length measuring instrument with large direct measuring range
Compliant with Ernst Abbe's comparator principle
Manual operation of measuring spindle
Air bearings for smooth manual positioning of measuring element (with laser reflector) and counter element
Object table height adjustment via pushbuttons (also positioning of predefined increment)
Laser correction with respect to environmental influences: temperature, air pressure (humidity optional)
Separate laser generator outside the measuring instrument, fed via optical cable, and laser beam cover
Computer-aided instrument zero point stabilizing and correction of systematic instrument errors (CAA)
Computer provided temperature measurement and computer-aided correction of temperature and measuring force influences
Constant measuring force over the entire measuring spindle setting range
Large object table with precision guidance in the Z direction and a loading capacity of 25 kg
Automatic reversing point detection with static and dynamic adoption of measuring values
Highly flexible within the application range (can be used for measuring both miniature and large measuring objects)
Mahr 828 WIN measuring and evaluation software and MS Windows®
Inner thread measurement supported by automatic Z positioning
