The Pressurized Liquid Gate Method
How pressurized fluid delivery systems prevent micro-bubbles and ensure uniform liquid distribution across the film plane.

As scanning resolutions migrated from 2K to 4K and 8K, micro-bubbles inside the index fluid became a major threat to image quality. The pressurized liquid gate was designed to solve this.
Eliminating Micro-Bubbles with Pressure
In a pressurized liquid gate, the fluid is pumped into the optical gate under controlled micro-pressure. This pressure dissolves tiny pockets of air back into the fluid and ensures that the liquid layer maintains an absolutely uniform, micro-thin profile across the entire aperture plane.
Recirculation and Filtration
Pressurized systems must continuously recirculate the fluid through micron-scale filters to remove suspended dust particles, emulsion flakes, and atmospheric contaminants that could otherwise act as focal points under high magnification.
