Biocompatible Sapphire Endoscope Lens Scratch Resistant Medical Grade Optics

This biocompatible sapphire endoscope lens is machined from single crystal sapphire, the hardest optical material used in medical devices today. With a Mohs hardness of 9, the sapphire endoscope lens resists scratches from surgical instruments, bone fragments, and abrasive cleaning tools that would permanently damage glass windows. The material is fully biocompatible and routinely used at the distal tip of endoscopes where the lens contacts tissue directly and must survive the harshest part of the instrument lifecycle.

Each medical grade sapphire rod lens is ground and polished to a 20-10 scratch-dig surface quality, then verified for dimensional accuracy and surface integrity. Sapphire transmits more than 85 percent across the visible range and offers outstanding chemical resistance to the disinfectants and cleaning agents used in operating rooms. This scratch resistant endoscope lens is available in diameters from 1mm to 5mm with custom lengths, and can be supplied with flat windows, rod geometries, or ball lens configurations for different optical functions. For device teams building minimally invasive surgery instruments, the sapphire endoscope lens eliminates the most common field failure: hazed and scratched distal optics.
