There are four factors to consider when selecting the appropriate LED light for a multispectral or hyperspectral application: LEDs have average lifetimes of tens of thousands of hours, as opposed to the average lifetimes of mercury and halogens which are only several thousand hours. This is useful in applications where there is a high sensitivity camera and the illumination system must compensate for any shortcomings or in an application where the lamp is required to match a specific spectral profile.Īnother advantage of LEDs in comparison to halogen or mercury lamps is significantly longer lifetimes. One advantage of using LEDs is the ability to boost specific spectrum where needed. Advancements in LED technology make it possible to provide broadband illumination using various combinations of LEDs of varying wavelengths. Mercury and halogen lamps have traditionally been used in multispectral and hyperspectral applications due to the nature of their broad spectrum.
