Hermetic & Light-Tight Cable Feedthrough for High-Vacuum & Precision Instrumentation

Dual-Cavity Hermetic & Light-Tight Cable Passage System

Technology Overview:

Routing electrical cables, fibers, or sensors into light-sensitive or vacuum-sealed environments without compromising isolation is a major engineering challenge. Standard grommets often leak light or disrupt internal atmospheric stability. This patented feedthrough system solves this using an internal dual-cavity structure that ensures complete light isolation and high hermeticity in a compact, durable unit.

Technical Architecture & Working Principle:

• Dual-Cavity Internal Geometry: Features a specialized dividing plate that splits the interior into two interconnected chamber cavities, forcing an offset path that blocks direct light transmission.

• Optimized Cable Routing: Includes protective entry and outlet covers engineered to strain-relieve cables while maintaining an airtight seal.

• Robust Environmental Isolation: Eliminates ambient light leakage completely while preventing dust, gas, or thermal ingress into sensitive enclosures.

Key Competitive Advantages:

• 100% Light Tightness: Complete optical isolation for ultra-sensitive light detectors and darkroom environments.

• High Hermeticity: Reliable seal for controlled-atmosphere, vacuum, or cleanroom enclosures.

• Modular & Scalable: Easily adaptable to multiple cable diameters, fiber optics, and electrical bundles.

• Maintenance-Free & Compact: Simple mechanical installation with no complex maintenance requirements.

Ideal Applications & Target Markets:

• Precision & Optical Instrumentation: Cameras, photonics test benches, and optical sensor enclosures.

• High-Vacuum & Cleanroom Equipment: Industrial processing chambers and scientific isolation boxes.

• Medical & Defense Devices: Sealed diagnostic hardware, darkroom test rigs, and sensitive signal processing units.

Licensing & Commercialization Opportunities:

Available for patent licensing (ES1309449U), technical adaptation, and joint industrial integration with manufacturers of laboratory, optical, and high-vacuum equipment.
