VC America Electronics' production-ready rotary scales (code wheels or gratings) are available to ship from stock, eliminating tooling costs while reducing evaluation and design time to expedite your product development process.
Our high-quality scales increase yield and performance with better patterning and fewer, smaller defects.
Ultra-precision patterning with nanometer photolithography improves repeatability and cycle-to-cycle accuracy for exceptional optical performance for all pitches down to 2µm.
Reflective and Anti-Reflective (AR) coatings and track patterns are optimized for each requirement, typically 850nm (Near Infra-Red), 650nm (Red LED), or 450nm (Blue).
Substrate materials include:
- Soda-lime glass for precision scales
- Stainless Steel (0.1-0.4mm thick) for ultrathin scales
- Low CTE Glass compositions for ultimate accuracy.
