Yes, 405nm is a very interesting wavelength. If you have goggles, or at least some UV-protective sunglasses, unfocus your 405nm and you can use it to find things that are fluorescent or phosphorescent. Some examples of fluorescence are red postage ink and bright hi-liters. Some examples of phosphorescence are the phosphors in fluorescent tube lights, peanut butter, some plastics, and glow-in-the-dark stuff.
