850 / 940nm 6mW VCSEL chip. Its application fields include not only particle sensors and laser medical, but also active optical cables (AOC), which fully guarantees the stability and flexible application of transmission media such as high-performance computing and data centers in the era of big data High demands.
The 850 / 940nm VCSEL chip is a multi-mode chip that uses advanced oxide isolation technology. Its oxide has a strong light limiting effect, which greatly reduces the threshold current and power consumption.
Compared with the wavelength drift of 0.3nm / ° C for LEDs and side-emitting lasers, the wavelength drift of this product is low (only 0.07nm / ° C), and the product performance is more stable. And the launch area is small, easy to collimate; the switching time is short, less than 100ps, the product performance is superior.
850 / 940nm VCSEL chip is suitable for all kinds of sensors. Proximity sensing, lidar, laser rangefinder, particle sensor, active optical cable (AOC), laser medical and other application scenarios can be widely used.
In terms of proximity sensing. Smart home products, such as automatic doors in hotels, restaurants and garages, automatic sensor faucets in shopping malls and homes, smart toilets, smart lamps, and home appliance control, have applications.
Lidar / laser rangefinder applications. Mainly used in tracking, imaging guidance, three-dimensional vision system, wind measurement, atmospheric environment monitoring, active remote sensing and other directions. Lidar can be widely used in automatic driving systems (ADAS), such as adaptive cruise control (ACC), front vehicle collision warning (FCW) and automatic emergency braking (AEB).
Laser medical applications. The application of VCSEL laser is not limited to skin beauty such as laser hair removal instrument, hair removal machine, beauty equipment, detector, laser instrument, etc. In clinical applications, VCSEL chips can be used in devices including myopia correction, retinal repair, tooth decay restoration, and molecular-level minimally invasive surgery.
Application of particle sensor. The particles in the gas phase include smoke and dust, and the particles in the liquid phase include bacteria, suspended particles, and blood cells. In some cases, I hope to be able to count accurately, such as hemocytometer, dust counter, etc. Sometimes, I want to be able to give a threshold, such as a fire alarm.
