Hermetic Optical Cells

The ability to employ optical systems in challenging environments provides designers with a wealth of opportunities to create smarter, safer, more-robust devices. Applications from gas-sensing to endoscopic surgery rely on hermetic cells in which optical processes can be carried out without interaction with or degradation from the surrounding environment.

This can result in very different specifications for what are generically termed “hermetic cells.” Whether designed to keep a gas or liquid in or out of an optical enclosure, a hermetic cell serves to isolate one environment from another. Perhaps the most frequent application of sophisticated hermetic cells is in medical devices like endoscopes or endocouplers to provide protection during autoclave sterilization. However, other applications such as protecting optoelectronics from harsh atmospheres or even sealing the combustible gas in a laser or IR analyzer from potential electronic ignition sources pose similar hermetic cell applications.

Access Optics meets these seal challenges head on. Our hermetic cells, consisting of glass-to-metal sealed sapphire windows laser welded to housings, flanges, tubes and other enclosures provide extreme protection. So whether your application involves laser-fusion reaction pressures, explosion-proof isolation, or 1000-cycle autoclave performance, we’ve got you covered.
