Yes, that is a laser diode
I dont own an optical mouse
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
Optical...If im not mistaken.
optical
laser light
While both optical in laser mice require a light source in order to detect movement, the difference between the two technologies are optical mice use LEDs as their light source while laser mice use infrared laser that cannot be seen by the human eye. Laser mice are also much more precise than optical mice due to a higher DPI tolerance.
There are quite some differences between an optical mouse and a laser mouse. One of the most noticeable differences is the type of rays coming out of the mouse. Now,we all know that from an optical mouse there is (usually) a red light coming out and on the other hand, the laser mouse does not produce such light. It produces an invisible laser beam which is harmless to humans. Also,they say,that laser mouses are much more precise than the previous generation mouses, 'thus making them much more valuable. And finally, you can use laser mouses on almost all surfaces (except glass, mirrors and air) which is quite useful in many situations. Of course,there are many people questioning which is better - the laser mouse or the optical mouse,but one thing is for certain - they may look the same,but they are definitely not the same thing.
There are two types of mice.One is optical mouse and the another is laser mouse.
A lazer mouse.
The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad.There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away.
A mechanical mouse has a ball & rollers on the bottom which moves the pointer. An optical mouse has a light instead, and you don't even need a mouse pad to use it.
Mouse ottico is an Italian equivalent of the English phrase "laser mouse." The masculine singular phrase translates literally as "eye mouse," "optic mouse," or "optical mouse" in English. The pronunciation will be "mow-SOT-tee-ko" in Italian.
