Our Infrared Fluorescence lamp, Alice, is a low-cost alternative to expensive VIS-only scientific lighting systems. This lamp provides pure visible light for infrared fluorescence photography.
Some molecules and minerals (among them some pigments) exhibit Infrared Fluorescence. This phenomenon is similar to Ultraviolet Fluorescence where a beam of ultraviolet light produces visible light emission. In the case of Infrared Fluorescence, a beam of Visible light generates an emission of Infrared radiation. This photographic method allows us to identify and locate cadmium pigments (cadmium red, cadmium yellow, cadmium green) and Egyptian blue. Infrared fluorescence photography is used in archaeology to detect even tiny fragments of Egyptian blue pigment.

Works on 110 -220 -240 V. This lamp is part of the Technical Photography KIT which is designed for traveler art experts. So, the lamp can work on both 110 V (as in the USA) and 220 – 240 (as in Europe).
Power emission. 1200 lumens
Tripod adapter. A standard photographic tripod adapter, size 1/4″.
Power plug policyAll of our tools work on both 110 V (USA) and 220 V (European) voltages. You can use them worldwide. We provide our tools with the original European power plug and a free power adapter to USA or UK standards depending on your choice.
Our intro to Infrared Fluorescence Photography
Infrared Fluorescence Photography (IRF)
Infrared Fluorescence photography is a useful method for the examination of works of art and archaeology. It is part of the Technical Photography documentation and allows to detect Egyptian blue and cadmium-based pigments.
Infrared Fluorescence phenomenonInfrared Fluorescence is observed in few rare minerals but also in a very common molecule, chlorophyll. Chlorophyll emits infrared fluorescence in the very near infrared. Indeed, its fluorescence is brighter in the IRF 850 image – where the 850 nm filter was used, allowing through the closest infrared. Notice that, on the other hand,the infrared fluorescence emission of the cadmium red swatch is almost unchanged since it happens at longer wavelength (over 850 nm ).
Applications in Art examination
