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:
