With the development of science and technology and the improvement of people's living standards, the increasing attention to non-invasive treatment has made great progress in the laser medical industry. For example, laser hair removal, laser hair growth, laser skin rejuvenation, laser pain treatment, blood oxygen pulse detection, endoscopy, etc. Brandnew's self-developed VCSEL chips of various wavelengths (670nm, 808nm, 850nm, 940nm) are widely used in the laser medical industry as an indispensable laser light source.
Laser hair removal
808nm semiconductor laser wavelength can take melanin as the target for accurate and selective hair removal treatment, black, yellow, white, brown and other colors of hair can be efficiently removed, fast and accurate, adsorption of melanin effect is particularly good, to meet the needs of customers whitening beauty.
The laser hair removal scheme uses 808nm VCSEL light source, the optical power is 20W, 50W, 100W, 200W, 300W, suitable for household hand-held hair removal equipment and large hair removal equipment. 808nm VCSEL diode Features:
Single wavelength, no side effects;
The effect of temperature is small, and the low wavelength drift is 0.07nm/℃.
Electro-optical conversion efficiency (PCE) up to 42%;
Moderate voltage and current, simple control circuit;
Permanent hair removal, no rebound;
Low power consumption, high efficiency
Laser hair generation
It has been proved that 850nm laser has better hair growth effect than 650nm red light, and has become the latest laser hair growth choice. The 850nm VCSEL laser has the characteristics of a patch package, which can increase the density of the light source, and greatly reduce the cost, while the volume will be greatly reduced. Since red laser is the peak of hemoglobin spectral absorption and can be strongly absorbed by hemoglobin, 670nm VCSEL laser irradiation of blood can restore the charging performance of red blood cells, improve the deformability and focusing of red blood cells, and reduce blood viscosity. 670nmVCSEL light waves stimulate the activity of hair follicles, causing dormant hair follicles to regrow hair. Common optical power is: 5-100mW(continuous or pulse).
Pulse oximetry
The detection of pulse is also a physiological index of routine detection. In outdoor light environment, 940nm light source and PD are usually used to detect pulse. In order to provide accuracy and enhance the ability to resist strong light, Sunbright introduced a 940nm VCSEL plus PD solution, which can improve the detection accuracy. In the detection of blood oxygen, Brandnew launched the 670nm VCSEL and 940nm VCSEL and PD programs, which can detect pulse blood oxygen and tissue blood oxygen, so as to understand the physiological condition of tissues, and can be widely applied to the evaluation of sports tissues. The principle is that the absorption coefficients of reduced hemoglobin (Hb) and oxygenated hemoglobin (HbO2) are different for different light wavelengths, as shown in the figure below. Another scheme is to use 850nm and 940nm invisible wavelengths, the absorption of light between the two hemoglobin is significantly different.
Laser pain treatment
Laser pain treatment is the use of polarized light to irradiate nerve pain points or acupoints, treating a variety of acute and chronic pain. For example, infrared polarized light pain therapy instrument, ultra laser pain therapy instrument, computer pain therapy instrument, etc. Its principle is 650nm/808nm VCSEL dual-wavelength composite light irradiation deeply penetrates tissues, soothing muscles and acupoint meridians. Common optical power: 0-400 mW (continuous or pulsed).
Brandnew can be supplied according to different customer requirements, wavelength: 808/850/940/980nm, optical power: 6mW-200mW or customized VCsels with different wavelengths and power.
