Micro Windows

Star-Optics manufactures precision micro windows that protect sensors and electronic instruments from environmental conditions while maintaining optical performance. Like their larger counterparts, micro windows feature two parallel surfaces, but their compact size makes them essential for miniature optical systems where space is limited.

These tiny optical elements must be precisely manufactured to avoid introducing aberrations or degrading image quality. Whether used in medical devices, fiber optic systems, or compact imaging instruments, micro windows are critical components that adapt to the needs of the overall system.

Applications

Medical endoscopes and surgical instruments use micro windows to seal optical channels while allowing light transmission. The windows protect internal optics from bodily fluids and enable sterilization without damaging sensitive optical elements. Biocompatible materials like sapphire are often specified for direct tissue contact applications.

Fiber optic systems incorporate micro windows in connectors and packages to protect fiber terminations from contamination and mechanical damage. Industrial sensors and imaging systems use micro windows as protective covers for detector arrays and camera modules. Consumer electronics including smartphone cameras rely on micro windows for lens protection.
