DT240
Rotary Stages

36 mm ultra-flat rotary stage (PCB motor), travel n × 360°, 100 mm aperture, rep ±0.001°, load 3 kg, speed 36,000°/s

Ultra-flat Rotary Stage with large aperture

The ultra-flat 36 mm flat-design stage combines a compact build height with an exceptionally large 100 mm aperture. The minimal installation height allows the light source, optics, and detector to be positioned extremely close to the sample. This reduces optical divergence, increases intensity, and minimizes noise — ideal for precise imaging and analytical workflows.

Ideal for highly stable imaging, analysis, and inspection tasks

Unlimited rotation range for flexible scanning and measurement routines

Compact design with only 36 mm height and a 100 mm aperture

Absolutely continuous rotation with resolutions up to 0.001°

Consistent performance even at high rotational speeds of up to 36,000°/s

Options:

Thin-section bearings or crossed-roller bearings for smooth and flat bearing configurations
Air-bearing version for speeds up to 600 rpm and maximum lifetime
Brake, rotation limiter, or mechanical hard stop
Purge air, extraction ports, integrated cable management

Application Fields

High-resolution optical and sensor setups, laboratory analytics, 3D analysis of live biological samples, wafer inspection, 3D topography and thickness measurement, lithography and mask handling, radar and RF technology, rotary platforms for compass systems, scanning applications, MEMS wafer mapping
