ThruSight-Theta

ALIO Industries’ ThruSight-Theta delivers ultra-low-profile rotary motion with true backside access for precision optical and advanced packaging applications. Featuring cog-free torque, a large through-hole design, absolute encoder feedback, and high continuous torque in a compact 25 mm form factor, ThruSight-Theta enables shorter optical paths, cleaner integration, and deterministic rotary performance for modern high-duty tools.

ThruSight-Theta — Ultra-Low-Profile Rotary with True Backside Access

When rotational precision and optical access must coexist, ThruSight-Theta delivers cog-free torque and best-in-class torque-to-height in a body just 25 mm tall. A generous 110 mm through-hole enables backside illumination and process access without extra stack height; absolute encoder feedback provides position on power-up; and 1 Nm continuous torque supports dynamic, high-duty trajectories with low jitter. 

Engineered as a drop-in, integration-friendly axis, ThruSight-Theta unlocks shorter optical paths, cleaner cable routing, easier service, and deterministic rotary behavior for modern tools. 

Ideal for: digital pathology and genome sequencing (clearer transmitted illumination), silicon photonics and advanced packaging (backside access for microlens placement and high-efficiency coupling), and flip-chip, bonding/de-bonding, thinning, and laser ablation where through-axis access is essential.
