High Power Violet 405nm Laser Writing Display

Violet 405nm Spartan Laser A 300mW 405nm Spartan laser pointer is used on fluorescent paint that is covered by normal paint to give the affect of ghost writing. One of the cool things about 405nm lasers how they can cause laser-induced fluorescence where a material (in this case paint) is excited by the 405nm wavelength and releases the energy of the lase beam in a different wavelength. Great for studying the structure of molecules and examing tumors. Thank you to Julius of I
