You can focus this slender, sharp-looking laser pointer to achieve the smallest possible dot at every distance by turning the gold ring at the front. The special 635 nm diode (within 3 nm of the theoretical limit of 632 nm) provides the extraordinary brightness. This laser outperforms other lasers of 670nm, 650nm, and even 645nm wavelengths. This is the ULTIMATE in a red laser pointer; FDA regulations do not allow brighter lasers for consumer use! It comes with a hard case for easy storage and transport. Caution: never stare directly into the beam of any laser or point it at anyone's eyes, regardless of the color or power.
