A manufacturer of medical endoscopes needed metalized sapphire windows with extremely smooth optically polished faces to allow for hermetic sealing into a Nickel 200 tube that was brazed to the sapphire.
Insaco recommended a unique manufacturing process at Insaco which would improve the overall quality of the sapphire window while allowing for improved hermetic sealing in order to autoclave the endoscope.
The manufacturing changes in the orientation of the sapphire window allowed for creating a strong hermetic seal which further enhanced the ability to autoclave the endoscope resulting in a 35% increase in overall yield on the final brazed sub-assembly.
