Nikon AS/AE Series
- These models use a wire-hung, air‑dampened compensator to stabilize the line of sight, effectively shielding it from magnetic interference and delivering precise leveling results.
- Built with rugged, waterproof housing—often nitrogen purged—ensuring fog-free optics and consistent performance even in wet conditions.
- AS‑2/2C: 34× magnification, 45 mm aperture, focus as close as ~1.0 m.
- AE‑7/7C: 30× magnification, 40 mm aperture, with even shorter focus down to 0.3 m.
- Lightweight and user-friendly, featuring double-sided continuous horizontal tangent drives (endless fine drive) for seamless, precise aiming.
- These levels achieve ±0.8 mm (AS‑2) or ±1.0 mm (AE‑7) accuracy over a 1 km double-run, which can be improved further using micrometer enhancements—±0.4 mm and ±0.45 mm respectively.
Automatic Levels for Surveying and Construction - Nikon AS/AE Series
kbse proudly presents the Nikon AS/AE Series automatic levels, engineered for unmatched reliability and precision in challenging environments. These rugged instruments feature waterproof, nitrogen-filled telescopes that resist fogging and perform brilliantly even in heavy rain or high humidity. The AS‑2 and AS‑2C models use a powerful 34×, 45 mm objective lens, delivering a minimum focusing distance of 1 m, while the AE‑7 and AE‑7C offer 30× magnification with a close focus down to 0.3 m for tight jobsite conditions. A wire-hung, air-dampened compensator provides automatic leveling, with a compensation range of ±12′ for AS models and ±16′ for AE models achieving 1‑km double-run leveling accuracy of ±0.8 mm and ±1.0 mm respectively. Setup and operation are streamlined with an endless horizontal fine drive, friction brake (no horizontal clamp needed), plus a standard optical sight lens and pentaprism mirror for erect bubble viewing during alignment. Compact, lightweight, and tripod-compatible, each unit includes a carrying case, adjusting pins, and lens cap making the AS/AE Series a reliable choice for surveyors, engineers, and construction professionals.
