To enable precise measurement of oxygen levels inside packaging bags and other sealed containers, Ocean Optics—the industry leader in microphotonics—has introduced the RedEye™ oxygen-sensing film. Combining its patented sensing materials with advanced optical sensing technology, this non-invasive oxygen-sensing film can rapidly detect the presence of oxygen and provide quantitative measurements of its concentration.

　　Accurate measurement of oxygen concentration is of great significance for medical and pharmaceutical applications. It can ensure patient safety during nursing assessments and when using respiratory devices, or indicate whether surgical instruments and pharmaceutical packaging have been properly sterilized and sealed.

　　The self-adhesive RedEye oxygen-sensing film can be attached to the surface of sample containers—such as blood bags, pill packaging, or care-analysis devices like single-use ventilator oxygen attachments—to non-invasively measure the oxygen concentration inside the package. The nano-porous gel coating patented by Ocean Optics boasts excellent resistance to chemical reactions, ensuring the sensor’s properties remain stable and providing reliable protection for the sensing film. Depending on the application, oxygen presence can be detected either by observing color changes in a handheld LED indicator or by using a fluorometer to directly measure the precise oxygen concentration.

　　The RedEye oxygen-sensing film can not only measure low oxygen levels in gases—down to as low as 0.005%—and dissolved oxygen in liquids (as low as 20 ppb), but it can also detect high oxygen levels, similar to those found in cellular tissues and during respiratory monitoring. In addition to these medical and pharmaceutical applications, the coating technology used in the RedEye oxygen-sensing film is also suitable for use in foods, beverages, fuels, and other hydrocarbon products.

　　Depending on measurement requirements, Ocean Optics can tailor sensor films to meet customers’ personalized specifications using three different coating methods. The RedEye oxygen-sensing film can be integrated into packaging for continuous monitoring, or applied to the surface of packaged products for post-production or R&D monitoring.
