1.Laser Hair Removal

The 808nm VCSEL has a natural advantage as a light source for laser hair removal devices. 808nm is most easily absorbed by melanin, while other cell tissues are weakly absorbed. The LEMON Photonics 808nm 70W VCSEL module has the advantages of high power density, laser direct to the hair follicle, and less damage to other tissues.

2. Laser physiotherapy light source scheme

Different tissue cells of the human body have different absorption conditions for different light waves.980nm laser has a significant effect on deep tissue pain and edema.LEMON Photonics 976nm HCSEL and EEL (edge emission laser) chip power can reach 18-45W high energy, tissue penetration depth up to 10cm, the generated energy can increase vascular relaxation and stimulate cell activity. 976nm+808nm dual-band stimulation physiotherapy can provide heat up in a few seconds and efficient analgesia, which is the perfect combination light source option for laser physiotherapy equipment.

3.Blood oxygen meter

The monitoring probe is composed of two VCSEL infrared light wavelength of 660nm+940nm, which monitor oxygenated hemoglobin oxygen content and hemoglobin oxygen capacity respectively, and measure the light conduction intensity through the blood vessels. Finally, the hemoglobin concentration and blood oxygen saturation are calculated by software analysis, and the instrument can display the blood oxygen saturation of the human body.
