- Laser pointer
- 2 AAA batteries
This Class 2 (<1 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 aluminum, and it uses two AAA batteries (included). The wavelength of the light is 650 nm. A momentary switch (normally off) controls the laser beam.
