FLoupeTM
FLoupeTM-2 (second generation) is a low-cost wearable eye-loupe based fluorescence imaging device capable of imaging visible dyes including fluorescein and 5-ALA.
This device includes battery-drive high-intensity LEDs for excitation/illumination and a small CMOS video camera with a flippable long-pass filter for fluorescence imaging and recording. One pair of long-pass filters sitting in a flippable frame is attached to the eye loupes for easily changing from fluorescence to color vision.
