How does the Velscope work?
Use Contrast to Show Adbnormal Tissue
The Velscope's blue light "excites" molecules (called "fluorophores") deep within the layers of oral mucosal tissues. In turn, these fluorophores emit their own light (fluorescence) in shades of green, yellow, and red. The Velscope's proprietary filter makes fluorescence visualization possible by blocking reflected blue light and by enhancing the contrast between normal and abnormal tissue.
