Re: Optical mouse vs. laser mouse A LASER mouse *IS* an Optical mouse, but not all Optical mice have LASERs, some have NON LASER LEDs for a light source. A LASER *IS* a light source, in fact, technically, it is considered what we call a "point source" in physics.
Most DIODE LASERS are in the infrared, I don't know about mice, but with other devices they are, and as such, appear invisible to the human eye.
A LASER, if not run through special optics first, will look like a point beam, very rectilinear, whereas an LED will be highly divergent (have a cone shaped light output).
HTH.

A laser mouse is not an optical mouse however people seem to assume that it is. An optical mouse like you said uses led and optics while a laser mouse in itself uses a laser and usually needs no LED lighting source. They are completely two different things and as far as I know laser mice just started to hit the market the past couple of years which also tends to make them just a tad bit more expensive then the standard optical mice. Its tough to tell whether or not a mouse is laser or not just by an led because now some manufactures are using them more for looks then anything. Most laser wireless mice have no led to use less battery.
Here for example logitech g5 Laser

The laser dpi is higher then the optical. You will also get better precision and battery life. | |

| Ryan, you ARE wrong. Do you know what "optical" means? First of all, a diode LASER **IS** a type of LED!!! DIODE LASERs are Heterojunction DIODE LASERS. The mouse might or might not use some of the same interferometric or other principles, but if it uses light, it IS optical. Period.
I am a photonics technician you are arguing with, BTW, are you an optics specialist? I am.
The reason the DPI is greater with LASER mice is because of the rectilinear quality of a LASER beam compared to the highly divergent nature of all other types of light sources, including non LASER LEDs.
LASER mice do NOT necessarily get better battery life. LASER DIODES consume much more electricity, depending upon the given diode. My MS Wireless Intellimouse Explorer 2.0 lasts 3 months or even more of HEAVY use on one set of batteries. I know that many LASER mice's batteries go dead and must be recharged within mere days or even hours.
Furthermore, if you knew what you were talking about, you wouldn't have types the term "Laser". They are "LASERs". LASER is an acronym for Light Amplification through Stimulated Emission of Radiation.
You are wrong sir.

Not sure why your arguing with me I realize that both use optics what im trying to say is there is a difference between laser mice and standard optical mice and thats exactly what you have stated in your post above. Have you ever heard someone say they bought a laser mouse and it just was a standard optical led mouse? There is a difference between the two and the difference is the light source.
I was in no way saying your technical language is wrong, but store bought mice come in two shapes and forms laser and optical. You could go through each technical detail comparing the two lighting sources, but the point is there are two types of mice available right now. The original poster wanted to know how to tell the difference between the two, which there is a difference you even stated in your post. What I was saying is telling the original poster that going out and buying an optical mouse is the same as buying a laser mouse is wrong its a different light source. Some people mistakenly claim that they have a laser mouse even though its an optical or optical led mouse instead of a laser or optical laser mouse. | |

1 edit | I do apologize however for saying "A laser mouse is not an optical" when I really meant to say LED, but being at work I sometimes get interrupted and don't have time to proof read. This might have caused the confusion of what I was trying to get out to the original poster. I refer to an optical led mouse as an optical mouse because of the fact thats how they are advertised and usually laser mice are referred to as laser mice. | |
