RSF Elektronik: Circular Graduations The use of measuring standards, principally in the form of linear grids, is an essential component of precision graduations. These precision graduations satisfy the highest quality requirements and define both the function and the precision of the measuring device.
A further focus is on the production of customer-specific RSF Elektronik graduations for particular requirements.
Incremental Graduated Discs and Reticles
Selected float glass Coefficient of expansion: (α≈8.5×10-6/K) Glass thickness: 1.0 ±0.1 mm Reticles scribed and broken Length resp. width tolerance: ±0.1 mm Outbreaks on edges: ≤ 0.1 mm
Sputtered chrome on glass Line width ratio 1 : 1 Graduation accuracy: ≤ ±2" Coaxiality graduation to outside diameter: 0.2 mm
