- even on glass. You work & play all over the place--and that means youre going to encounter all sorts of work surfaces. A glass desk or shiny table shouldnt stand in your way. Thats why we created Logitech Darkfield Laser Tracking™, featured in the Logitech Anywhere Mouse MX™ & the Logitech Performance Mouse MX™. Darkfield tracks on surfaces like clear glass* & lacquered desks that stump optical mice & standard laser mice. So now your mouse works wherever you do. Its all in the details. Optical & traditional laser mice use irregularities in the surface to track the direction & speed of your mouse. The more irregularities on a surface, the easier it is for the sensor to track your movements. But use your mouse on a smooth, glossy surface like clear glass, & there just arent enough imperfections for your standard mouse to work. This is where Darkfield Laser Tracking comes in. Darkfield uses the smallest possible details to create a micro-road map of the surface--so you get better precision on more surfaces. Can this mouse do everything? Just about. Keep in mind, however, that we havent designed the first two mice with Darkfield Laser Tracking for gamers or for those working on laboratory-grade clean glass. If youre making lightning-fast maneuvers & need gaming-grade cursor speed, take a look at the Logitech G9x Laser Mouse. & if youre working on exceptionally clean glass, you may have to wait until the dust settles. For surfaces with fewer than 44 microscopic details (per square millimeter) that are less than 5 µm wide & 1.5 µm thick--to give some context, a stra
