How to distinguish visible light from invisible light?

Let`s say the details of "Visible light" "Invisible light" . For light that cannot be seen with human eye, see Electromagnetic radiation. For other uses, see Light (disambiguation) and Visible light (disambiguation).

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

The wavelength of JRT Laser Distance Sensor is 620nm-690nm, the regular model of U81/U85, M703A/M88B, B605B/B87A belongs to visible light. But we can customize Invisible light for you, if your laser measurement projects have that requirements, pls contact us. Thanks for choosing JRT.
