Lead Glass Shields

Our Lead Glass Shields are used as a barrier to prevent X-Ray radiation while allowing a safe and clear view into the vacuum system. The shield is mounted to the atmosphere side of a standard CF type Zero-Length viewport using longer than standard bolts (bolts not supplied). The vacuum seal is made by the Zero Length Viewport.

Features:

•  X-Ray Shielding
•  Lead equivalent 2mm (.078”)
•  Light transmission 85%
•  Refractive index 1.76
•  Can be mounted with the glass removable or non-removable
•  Leaded Glass can be replaced
•  Other flange sizes available by special order

Additional Information:

• Lead Glass is not tempered or fire rated.
• Hairline scratches are inherent in the manufacturing process of this glass.
• Wipe smudges with a dry cloth, never use a wet rag.
• Wipe fingerprints and grease off immediately to prevent tarnishing. If a dry cloth doesn’t remove smudges, use alcohol.
