Lasers in the classroom

Hello guys,

I finally decided to take a picture of this great little device which is used by the teacher/instructor in the classroom to project an image on the *big screen* and/or to show the classroom a piece of paper i.e


Neverthless,
The device itself has 4 individual <1mW Class II 650nm diodes which project the light onto the desk and make a box. The outline of the lasers are used to accurately place the piece of paper on the desk in a way that it will be properly shown on the *screen*

Below are some pictures to better show the device:






Also took a picture of the label. Note: It is VERY hard to read due to my iPod's camera!!!!



The specs are below:

Class II
Wavelength: 650nm-660nm
Maximum output: <1mW


Hope you enjoyed this thread, I will continually be on the look-out for anything new :beer:

Wow. Such beam. Much laser. Very light.

Are you telling me it wasn't operating in the photo? I could have sworn it looked like it was turned on. Its like, some IMAX 3d real life shit yo.

you could take the four diodes out that and make the world's weakest 4 diode laser pen :crackup:

Whatever you do, don't project directions to where you're going, on your eye.

LOL! :crackup:
