Glass Desk 400 - 800 DPI Requires high reflectivity sensors to work. The polling rate, measured in Hz, determines how often the mouse reports its position to the computer, with higher rates providing smoother on-screen tracking.
How an Optical Mouse Works Internally: From LED to Sensor
A red or infrared LED emits light onto the surface below, illuminating microscopic textures and patterns that are invisible to the naked eye. Surface Type Recommended DPI Performance Notes Hard Mouse Pad 800 - 1600 DPI Optimal tracking with minimal acceleration.
The fundamental principle remains identical: capturing sequential images to calculate motion, ensuring precise control in any computing environment. From Light to Motion As the mouse moves, the surface pattern shifts between these rapid-fire images.
How Optical Mouse Works Internally: From LED to Sensor
Mechanical mice suffer from friction, worn-out parts, and frequent cleaning to remove accumulated debris. Highly reflective surfaces like mirrors or polished metal can confuse the sensor by bouncing light back into the camera incorrectly.
