Logitech Announces Mice With "Darkfield" Tech

By - Source: Tom's Hardware US | B 28 comments

It reads glass!

We like optical mice and wouldn't dream of going back to the old, mechanical ball and roller ways – unless if we're trying to use our mice on a surface that's difficult to track on. Those of us with fancy glass desks know that getting an optical mouse to work on glass is a futile effort without the addition of a mousepad. Thanks to Logitech's new "Darkfield" technology, tracking on glass is now possible.

Logitech today announced two new premium mice, the Anywhere Mouse MX and the Performance Mouse MX, that will track on clear glass at least 4 mm thick as well as lacquered desks.

Perhaps just as good news is that these new mice also work with Logitech's unified USB nano receiver.

    I never have had glass but good to know, I am thinking about getting glass tops to protect my cherry desk and this would be really nice to have!

    What's its DPI. Could be a descent gaming mouse for those who prefer wireless.

    I always have a mousepad in my laptop bag. I'd find it kinda weird not to use one really ^_^

    Interested. Definitely would like some amplifying information Like DPI and does reading on glass affect battery life, if at all.

    will any of these be available in a "lefty" version?

    You know, I'm a dedicated lefty myself, but I could never stand to use a mouse with my left hand. Maybe its because I put more focus on the keyboard. With the exception of playing games, moving from the keyboard to the mouse is an annoyance. I keep my stronger left-hand doing important stuff on the keyboard, and leave menial mouse-duties to the inferior right-hand.

    Why Darkfield? Is the lazer for it a black red that reminds us of the abyss?

    Isn't what laser mice are supposed to be able to do?

    "Just about. Keep in mind, however, that we haven’t designed the first two mice with Darkfield Laser Tracking for gamers or for those working on laboratory-grade clean glass."

    I'm wondering if the mouse "feet" will stick more to glass and make the mouse hard to use? The little teflon pads under the mouse will stick to the glass surface. Are they using something different?

    Forget asking about the DPI as searching the Logitech website will just send you in circles.

    Here is the closest you will find to an answer and no, the first two mice are not Game Quality as the following link states.,en&pcid=6094

    for crappy mice, glass that has a readable surface behind it isn't an issue (usually 1/8th inch or so). But for higher end mice, especially gaming oriented, they have a limited reach, the smaller the better, so your mouse won't track when you pick the mouse up. I have built a mouse pad or two out of some acrylic and some uv reactive paint, it's kind of difficult to get infrared mice to read on this kind of surface because the IR signal is diffused rather than reflected. laser mice *shouldn't* have as much of an issue provided that the glass isn't too thick and does indeed have something of color or opaqueness behind it. Having said all that, the title of this article clearly makes me want to read about "darkfield" tech or whatever but no mention of it is included. disappointing to say the least. Maybe i will mod my mouse with a red laser so i can use glass/acrylic.

    That receiver looks so small, how do you pull it out of the USB port?

    BlueTrack is older then you think it's like a year old already. Last time i remember it's a Blue LED that Microsoft uses with a wide angle lens which allows for much more surfaces for the mouse to work on, no longer a lazer! But it does not work on glass or reflective surfaces as far as i remember.
