Product Information
1H,2H-Cyclohepta[D]imidazol-2-one is a chromophore that has resonance at wavelength of 370 nm with an optical density of 1.4 when exposed to an electron beam. The azulene group in the molecule causes it to absorb light and become excited. This excitation leads to the emission of light at a wavelength of 450 nm, which can be seen with a laser. The long-term recording properties are due to the stability of this chromophore as well as its ability to be sensitized by nitrogen atoms in the auxochrome.
