Cap/Window User Instructions and Guidelines

Redfish Photonics manufactures cap/window assemblies using a proprietary adhesive sealing process.

Specifications for adhesive and seal

Precautions

Please contact Redfish Photonics prior to using solvents on or near cap/window seal.
Ensure the surface to be joined with the cap flange is flat to ensure cap to window seal is not compromised by improper torque.

Cleaning Instructions

For sapphire windows: Alcohol and a cotton swap may be used to clean windows and caps. The extended use of other solvents can soften the sealing adhesive and may compromise the integrity of the seal. Contact Redfish Photonics prior to using solvents to clean the cap/window assemblies.

For other window materials: contact Redfish Photonics for appropriate cleaning materials and procedure. Some windows contain coatings that may not be apparent to the naked eye. Be aware of the window material and possible coatings prior to the cleaning process.

Test and Inspection

Each assembly is inspected and tested prior to shipping.

Air pockets in the adhesive may occur between the window and cap in the flat area between the cap aperture and inside edge of cap depending upon the surface area. This will not affect the function of the seal. Voids, cracks, and air pockets are not permissible in the critical seal area between the window edge and inside wall of the cap.

Each seal is guaranteed leak tight to 1.0X10-8 cc/sec He Gas unless otherwise specified on Sales Order.
