Total DOF
For 3 DOF with 25 mm travel and 100 nm resolution, a coarse–fine hybrid provides the best balance of range, precision, and flexibility.
Performance Estimates
Travel / resolution ratio
Within single-stage range
Est. resonant frequency
f_res = (1/2π)√(k/m) with representative stiffness
Est. settling time
t ≈ 3/f_res
Error Budget Estimate
Abbe error
δ = L × α (architecture-dependent offset)
Thermal drift
α_CTE × ΔT × L (assumes ±0.5 °C)
Stage repeatability
Representative for architecture type
RSS total (1σ)
√(Abbe² + thermal² + repeatability²)
Alternative
Alternative architecture
Stacked serial stages are simpler if the resolution requirement can be met without a piezo fine stage.
