I'm being a bit pedantic - I'm pretty sure the visibility of the wavelength does matter (slightly) for lower power lasers, as visible lasers will allow your eye to react to the laser (by looking away) before serious damage - again only in low power lasers (like laser pointers). If it's not visible I'm not sure that your eye will react quickly enough to prevent damage. |
