About Ultraviolet Sensors

Ultraviolet (UV) radiation constitutes a portion of the electromagnetic spectrum from 100 to 400 nm, and is further subdivided into three wavelength ranges: UV-A (315 to 400 nm), UV-B (280 to 315 nm) and UV-C (100 to 280 nm). Much of the UV-B and all of the UV-C wavelengths from the sun are absorbed by the Earth’s atmosphere. There are also many artificial UV light sources available that output a select wavelength range or offer a broadband UV radiation source.

UV-A radiation is important in material sciences and has numerous photobiological effects. For example, exposure to UV radiation can cause plants to produce secondary compounds, including flavonoids and antioxidants. Apogee's new UV-A sensors offer a low-cost option for detecting UV radiation from 300 to 400 nm and are calibrated in energy flux units of Watts per square meter.

Typical Applications

Applications include:

• UV radiation measurement in outdoor environments and laboratory settings

• Measuring the filtering ability and stability of various materials

• Monitoring UV radiation in horticultural operations and environments
