Quick-Access Viewport Doors offer a fast and convenient solution for manually loading and unloading samples in high vacuum environments. These doors are hinged and secured with a swingaway hand knob locking mechanism, enabling tool-free operation and reduced system downtime. The integrated viewport is constructed with Corning® type 7056 glass fused to a Kovar® nickel-iron transition sleeve, ensuring thermal and mechanical stability.

Each unit comes with a Viton® elastomer seal, delivering reliable vacuum sealing and bakeout capability up to 150°C (302°F). For higher temperature demands, optional Kalrez® elastomers are available.

Choose between: Clearance hole versions for installation on tapped chamber ports and Tapped hole versions for installation on clearance ports

Industry Applications

Quick-Access Viewport Doors are ideal for semiconductor fabrication, vacuum coating, thin-film deposition, space simulation, and materials science research. Their rapid manual access and high-vacuum compatibility make them essential in cleanrooms, aerospace labs, academic institutions, and precision R&D environments requiring both visibility and reliability.
