Laser sensors: A controlling interest
Sensing the details
What does a mouse do? Fundamentally, it allows you to control your cursor. And the best measure of cursor control is the accuracy with which the mouse translates the movements you make with your hand.
How precise is your mouse? Logitech mice use advanced sensors to make sure that whether youre clicking links, dragging text, or opening new appsthat whatever youre doingyour computing experience is seamless.
We achieve precision by designing miniature sensors. These sensors take lots of little pictures of the surface below the mouse, interpret those pictures, and translate the movement your hand makes into movement on your screen.
Details, details
There are two kinds of sensors: optical and laser.
Mice with optical sensors track the surfaces beneath them using the available light and an LED lamp.
In 2004, Logitech introduced the first mouse with laser tracking. Laser sensors, compared to optical, produce far more illuminationboth of the surface and of the contrast created by, literally, specs of dust on the surfacerevealing a wealth of details even on glossy surfaces like highly polished wood. And that means your mouse can track motion precisely on many surfaces, without lags or jitter.
Glass. The final frontier.
Logitech mice that are built with Logitech Darkfield Laser Tracking use the smallest possible details to create a micro-road map of the surface. That means these mice can track on glass.*
Track tested
We rigorously test all of our laser mice on a wide variety of surfaces to make sure your mouse is free of tracking flaws.
* Mice with Logitech Darkfield Laser Technology cannot track on glass that is 4 mm thick or less, which is not much larger than the head of a pin.
