Feature

This System

Typical Competing Systems

Vacuum Speed

15–20 min to high vacuum (≤5×10⁻⁵ Pa)

Often 30+ min for similar vacuum levels.

Film Uniformity

±3%–5% thickness deviation

Typically ±5%–10% in entry-level models.

Chamber Material

304 stainless steel (high corrosion resistance)

Some use aluminum or lower-grade steel.

Modularity

Supports 1–3 evaporation sources (expandable)

Fixed configurations common in low-end systems.

Footprint

Compact (500×360×420mm for desktop model)

Larger benchtop units often >600×500mm.
