– 1 inch adapter only, no pedestal mounting post.
he New Focus 8401 picomotor rotary stage is a compact, motorized precision rotation mount used primarily in photonics and optics labs for angular positioning of optical components like waveplates, polarizers, beam‑steering elements, and similar optics. Key attributes:
- Motorized rotation with picomotor actuation — ultra‑fine incremental movement (resolution better than ~0.2 milliradian, ~0.011°).
- Compact & low profile — ~0.63 in. (16 mm) thick overall.
- Adapters included — typically for 1″ optic diameter (25.4 mm) and often a 0.5″ adapter as well.
- Stainless‑steel body — stable structure for precision optical setups.
- Use cases: fine angular alignment, automated optical experiments, beam path control, and integration with motion control systems.
