Sapphire Domes

Sapphire DomesSapphire dome offers better optical performance and durability over other substrate materials. It  provides a very strong and durable protective environment to house other optical components, and is useful over a wide transmission band (150nm - 6000nm).


Bluebean Optical's Sapphire domes are ideal for high durability and accuracy applications including high speed missile domes, viewports, and other front surface optics.


With our highly repeatable 5-axis spherical machining center and scooping tools, we fabricate optical domes of Sapphire, Quartz, Glass, Silicon and Germanium in sizes up to 200mm diameter.

Our Capability Features:


- High form accuracy

- Flexible Substrates

- Strict  process control

- Low running costs

- High throughput

- Quick turnaround
