Red light is one of the great inventions of mankind in the 20th century, and it is widely used in many fields. The clinical value of red light irradiation has been affirmed at home and abroad. It has a certain effect on health and inhibiting human aging.

The red light meter uses the most advanced semiconductor technology and methods today:

(1) Adopt ultra-bright luminous tube LED, dot matrix type light source, light energy is balanced.

(2) Narrow spectrum, pure chromatogram, high monochromatic brightness, small wavelength error λ±2nm, similar to the wavelength of 632.8nm red helium-neon laser, and strong specificity.

(3) The light source emits red light directly.

(4) It has low power consumption, high efficiency, high power, no need for cooling, deep penetration, and large irradiation area.

(5) It can be used at close range, the irradiation site is accurate, no trauma, no pain.

(6) It is safe and reliable and can be used for a long time.
