What Is a 980nm Infrared Laser Module?

A 980nm laser module produces near-infrared (NIR) light at a wavelength of 980 nanometers. Unlike visible red, green, or blue lasers, a 980nm laser beam is mostly invisible to the human eye, making it useful for specialized industrial and scientific applications.

980nm lasers are widely used in machine vision systems, industrial automation, positioning equipment, optical sensing, and research projects where invisible infrared illumination is required.

Is a 980nm Laser Visible?

A 980nm laser is classified as a near-infrared laser. Most people cannot see the beam directly under normal conditions.

However, some camera sensors, night vision equipment, and infrared-sensitive devices can detect the beam.

Because the beam is largely invisible, proper laser safety precautions should always be followed.
