Laser Pointers (Available in Red,
Pen shape laser pointers are excellent light
source for ray optics and useful tools in presentation. These new, inexpensive
and safe class IIIb 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. The red laser projects a light beam at a
wavelength of 650nm, the green laser emits a light at 532nm, and the
blue laser features a wavelength of 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.
