CF-100 Vacuum Sight Glass — compact CF-flange vacuum viewport (CF100) for high- and ultra-high-vacuum systems. Metal-sealed optical window for real-time observation of vacuum chambers, scientific instruments and UHV process tools.
CF-16 Vacuum Sight Glass — compact CF-flange vacuum viewport (CF16) for high- and ultra-high-vacuum systems. Metal-sealed optical window for real-time observation of vacuum chambers, scientific instruments and UHV process tools.
CF160 vacuum sight glass (CF160 viewport) is a compact ConFlat® (CF)-flanged vacuum viewport designed for high-vacuum and ultra-high-vacuum systems. These viewports use a metal-to-glass (Borosilicate / Quartz (Fused Silica) / Sapphire / Barium Fluoride / Calcium Fluoride / Zinc Selenide) sealed construction that preserves UHV integrity while providing optical access for process monitoring, alignment, and inspection. Typical materials include stainless steel housings with sapphire, quartz (fused silica), or high-grade borosilicate windows.
CF-20 Vacuum Sight Glass — compact CF-flange vacuum viewport (CF20) for high- and ultra-high-vacuum systems. Metal-sealed optical window for real-time observation of vacuum chambers, scientific instruments and UHV process tools.
CF200 vacuum sight glass (CF200 viewport) is a compact ConFlat® (CF)-flanged vacuum viewport designed for high-vacuum and ultra-high-vacuum systems. These viewports use a metal-to-glass (Borosilicate / Quartz (Fused Silica) / Sapphire / Barium Fluoride / Calcium Fluoride / Zinc Selenide) sealed construction that preserves UHV integrity while providing optical access for process monitoring, alignment, and inspection. Typical materials include stainless steel housings with sapphire, quartz (fused silica), or high-grade borosilicate windows.
CF-25 Vacuum Sight Glass — compact CF-flange vacuum viewport (CF25) for high- and ultra-high-vacuum systems. Metal-sealed optical window for real-time observation of vacuum chambers, scientific instruments and UHV process tools.
