Collect the data that matters,

Continued population growth and urbanization is projected to add 2.5 billion people to the world’s population by 2050.

The resulting strain on utility infrastructure and environmental systems is leading to a worsening of water and air quality that impacts our global communities. Continued, real-time monitoring of these resources and systems protects families from contaminated drinking water, our environmental ecosystems and can optimizes industrial processes. Many chemical compounds have a specific, predictable behavior when exposed to UV light. Their absorbance or fluorescence can be used to measure the presence and concentration of a wide variety of contaminants present in water or air.

Optan LEDs and LED-based solutions offer a compact and reliable source of UV light that provides accurate, system-wide data for water quality, ozone and process monitoring measurements.

Kinds of Air Disinfection Methods

Air purifiers remove particles and other pollutants from indoor air using cartridge filters to trap contaminants. These High Efficiency Particulate Air (HEPA) filters are capable of removing 99.97 percent of airborne particles, however HEPA filters do not remove the volatile organic compounds or small pathogenic micro-organisms, like influenza.

Widely used humidifiers add moisture to the air to prevent irritation of the skin, nose, throat and lips. However, humidifier reservoirs require frequent maintenance to avoid the formation of bacteria and mold which can contaminate air. Current devices depend on preventive maintenance using chemical cleansers which can damage humidifier material and result in residual odor.
Why UVC Disinfection

Traditional UVGI systems are based on germicidal mercury lamps. Though effective, these systems do not scale well in terms of size, performance and cost to address the needs of consumers. In contrast the compact, high intensity, on-demand operation of UVC LEDs permits compact innovative designs where the LED can last for the lifetime of the appliance.
Benefits of UVC LEDs
UVC disinfection remains the sole proven, practical and cost effective solution for addressing true microbial safety without impacting odor or taste. Historically germicidal mercury lamps have been the trusted UVC source. However, durable UVC LEDs are poised to replace these with innovative compact product designs.
- Proven, maintenance-free true UVC germicidal performance
- On-demand operation to fit user needs and behaviors
- Compact and portable product designs
- Non-toxic, mercury free peace of mind

Lose The Lamp

Lamp-based systems require grab sample collection or expensive instruments to generate data. UVC LEDs enable data capture from distributed devices that are much smaller, more robust, less expensive and with longer maintenance cycles than lamp-based systems. With UVC LEDs, application-specific devices deployed in networks can generate over a million data points in real-time for better decisions.

Using UVC LEDs eliminates 40–80% of instrument costs.

Key Applications

Water Quality Monitoring

Clean water is a vital resource for human consumption and industrial processes. Optan UVC LEDs can enhance online, real-time measurements and data acquisition with low power usage and high accuracy.

Gas & Air Sensing

Exposure to air pollutants like ozone, even at relatively low levels, can result in harmful conditions like reduced lung function. UVC LED-based gas sensors can deliver highly accurate absorbance measurements of pollutant concentration in the ambient air.

Process Monitoring

Production environments like power generation and petrochemical plants require continuous, maintenance-free monitoring of industrial systems that provide sensitive measurements to key contaminants and compounds.

Future Applications

With a wide range of wavelengths, ultra-compact size and proven reliability, the list of applications for Optan LEDs is constantly growing. As the need for systemic environmental monitoring becomes important on a global scale, Optan is becoming a key component in next generation sensors.
