       This Class IIIa (<5 mW) laser pointer can be used with the Vernier 
        Photogate to produce a gate that is wider than the normal 7.5 cm 
        spacing, making it possible to measure the speed of an automobile
        or of a person running. The laser case is made of aircraft 
        aluminum, and it uses two AAA batteries (included). The wavelength
        of the light is 650 nm.
