Laser Pointers

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. The red, green and blue 
lasers offer different wavelengths for interference and diffraction experiments.

The use of different color lasers will make any classroom presentation more effective and interesting. 

Red Laser = 650nm     Green Laser = 532nm     Blue Laser = 405nm
These lasers operate on two AAA batteries, draw a current of less than 
60mA, and produce 5mW of power. Dimensions: D=13mm, L=165mm.
