Precise encoder discs
Encoder discs produced using laser evolved electroforming
A combination of laser processing and electroforming means encoder discs and strips can be smaller, more accurate and produced in any volume.
Precision Micro can economically produce metal encoder discs and strips, for motion control, positioning and measurement with both standard slot counts and bespoke requirements using its LEEF (Laser Evolved Electroforming) process.
Apertures of less than 15 microns can be achieved with high repeatability, smooth walls with optically sharp edges, without the use of prohibitively expensive glass master tooling.
Burr-free, stress-free discs and strips are formed by electrodeposition, atom by atom, onto a digitally patterned mandrel and can be either totally flat or multi-level.
The multi-level process can produce discs and strips that are exceptionally thin in the feature area to facilitate a crisp, well defined light pulse, while being thicker in other areas to meet mechanical requirements.
“Once again, Precision Micro’s development engineers have pushed the boundaries of an existing technology with outstanding results,” said Anthony Marrett, Managing Director. “The new LEEF process will enable designers to produce ever smaller digital optical disc encoders, opening up new possibilities for miniaturization”
