What is the difference between a laser mouse and an optical mouse?
“The difference between a regular optical mouse and a laser mouse is the light used to track movement. A regular optical mouse uses an LED light in the optical engine, while a laser mouse uses a laser to track movement. The more dots per inch (dpi) a mouse can track, the more sensitive and accurate it is. A typical optical mouse tracks between 400dpi and 800dpi, while laser mice track more than 2,000dpi.
