Laser induced Fluorescence spectroscopy (LIF) can be used to complement other spectroscopy techniques such as XRF and reflectance spectroscopy to identify and characterise materials. LIF hyperspectral imaging at standoff distances of up to tens of metres can be used to conveniently analyse any area on a monument/object from the ground level without having to move the instrument. It can also operate at close range to give microscopic fluorescence spectral images.
Laser Induced Fluorescence Spectroscopy (LIF) takes advantage of a laser source to excite a material to a higher energy state. The subsequent relaxation of the material to a lower energy state produces photon emission through the process of fluorescence. In many cases the resultant emission spectrum can show characteristic spectral features, allowing discrimination of materials. It is particularly useful for characterising organic materials and semi-conductors. We offer LIF spectral imaging in a range of working distances from centimetres to tens of meters. We use a range of excitation laser sources from UV to Near Infrared. The detection spectral range is 400-1000 nm.
