Case study: Glass wafers for covering and protecting optical sensors
Optical sensors often require a transparent, mechanically stable and contamination-resistant cover at wafer level. PLANOPTIK provides customized glass cap wafers – either as blank glass for protection or as structured glass with cavities, channels or blind holes for added functionality.
During assembly, the glass wafer is aligned and bonded to the sensor wafer, forming a robust glass–silicon stack. After bonding, the stack is diced into individual dies, automatically encapsulating and protecting each sensor with its glass cap.
These optical sensor modules are used in industrial inspection and automation, medical imaging, consumer electronics, and automotive camera systems – where clean optics and long-term stability are critical.
