'Darkfield' Lasers give Mice create along glaze over

Darkfield Laser Tracking might sound like something the Death Star uses to find and kill pesky Rebel spaceships, but it is in fact much more mundane, albeit useful. The tech is in fact a new trick from Logitech to solve a problem that has plagued more stylish offices since the mouse-ball rolled out of town.

Two new mice have the mysterious Darkfield Lasers which enable them to track on glass. This means that you'll not only be able to work at the dining table, but at that expensive crystal and chrome desk that has sat useless for all these years.

Regular optical and laser mice track marks on the surface of the table, but glass is too flat and too see-through. The new lasers actually peer inside the glass and reveal its microscopic imperfections. The result is that these two new mice, the Performance MX and the smaller Anywhere MX, will track on any surface except laboratory grade glass (and regular glass needs to be more than 4mm thick. If it isn't 4mm thick it's probably not safe to use as a table anyway).

Both mice also come with Logitech's tiny set-and-forget USB receiver and weighted spinny-wheel for fast scrolling. The small Anywhere MX is $80, the bigger Performance is $100.
