Multispectral Sensors

Capture near-infrared radiation (NIR) and ultraviolet light invisible to the human eye

A standard visual sensor collects red, green and blue wavelengths of light. Multispectral sensors are able to collect these visible wavelengths as well as infrared radiation and ultraviolet light (non-visible wavelengths).

Multispectral sensors are instrumental in plant health and management. They can pinpoint nutrient deficiencies, identify pest damage, optimize fertilization and assess water quality. Detailed insight can also be secured using algorithms from Vegetation Indices.

Multispectral sensors fall into two categories: modified and multiband.

Modified sensors are created when a special filter is placed inside a standard visual sensor. As a result, modified sensors collect three bands of light at once through the same lens. Filters can come in many different formats to display different combinations of spectral bands.

Multiband sensors are manufactured specifically for multispectral data collection. Each band is collected separately so there is no need for multiple flights. Multiband sensors also enable you to mix different band combinations to meet your needs.
