MOLDED GLASS DOME CAPABILITIES
Maximum Operating Pressure
Up to 30,000PSI
Glass domes can go to over 100,000psi. However, dome mounting is the limiting factor in pressure systems. The maximum operating pressure is determined by how the dome is mounted. Over time mounting may contribute to degradation of maximum operating pressure. External Pressure only (convex side). Never operate with internal, concave side pressure.
Better than 10/5 scratch/dig
Proprietary Rayotek Non-contact glass molding technologies introduce no scratches or mold marks on the glass surface. Both surfaces are pristine, better than ground & polished.
Proof pressure testing up to 100,000PSI
Rayotek maintains a proof pressure testing lab with NIST traceable measurement capabilities. Test equipment includes: pumps, gauges, a confocal laser surface defect measurement station & furnaces. Glass domes & coupons can be dried to a specified dew point to avoid damaging glass during non-destructive proof pressure testing.
Most fluids & gasses
Can be tested in virtually any chemistry; some chemistries will require special tooling & fixturing for safety & reliability of measurements.
Max temp 1750 C
Rayotek has air & atmospheric controlled furnaces up to over a meter in size for testing.
Helium leak checking
Can measure He leak rates down to 5x10^-12 Atm-cc/sec helium.
Dry MOR bar, tensile & flexural testing
Testing can be performed in air or a controlled atmosphere. Test pieces can be dried in a controlled manner to reduce micro crack moisture impact on test results.
340nm to 2.3 microns
Highest quality, traceable optical borosilicate glass is used for optimized thermal, mechanical & chemical resistance.
High quality, very homogeneous borosilicate glass is exceptionally durable in high mechanical, thermal &/or chemical environments.
Rayotek mounts domes into flanged & threaded metal housings. Go to Rayoteksightwindows.com for more information
Stainless steel 316
Good for chemical, industrial & pharmaceutical applications for moderate temperatures.
Excellent for ultra-high pressure & temperature applications. Also for situations where high strength to weight ratio are critical such as aerospace & space.
Ideal for chemical & temperature extreme environments.
Low cost option for industrial applications. Ideally should be treated to avoid rust.

For custom sizes a mold & tooling charge will apply. However, for quantity runs the mold/tool cost amortized per dome is often still lower than grinding & polishing
