For most indications, infrared is more versatile because it penetrates more deeply. The Apollo is in the infrared range with a wavelength of 810nm. VR, which is often around 660nm, is better for skin problems, but is not as versatile as an IR probe.

The difference between the visible red light and infrared light lies in their wavelengths. The visible red light is a part of the electromagnetic spectrum with the wavelength of 622nm to 780nm. The infared light or IR light has a wavelength of 700nm to 1mm.
