Pen shape laser pointers are an excellent light source for ray optics and useful tools in presentation. These new, inexpensive and safe classIII diode laser pointers can be used in physics labs to study reflection, refraction, and other light properties. This green lasers offer a 532nm wavelengths for interference and diffraction experiments. Requires 2 AAA batteries. Read Laser warning before use.
The use of different color lasers will make any classroom presentation more effective and interesting. The green laser projects a light beam at a wavelength of 532nm.
These lasers operate on two AAA batteries, draw a current of less than 60mA, and produce < 5mW of power.
Dimensions: D=13mm, L=165mm.
