VCSEL devices are widely used in distance sensing and 3D sensing. When VCSEL arrays are used for TOF modules, especially for dTOF systems such as LiDAR, the peak power, operating current, operating voltage, conversion efficiency, near-field and far-field optical characteristics and other parameters of VCSEL in the case of narrow pulses (usually nanosecond) are very important for chip suppliers, packaging service providers, module integrators, etc.

In order to meet the demand of VCSEL industry chain for narrow pulse LIV and near-field and far-field tests, Cotai Optical Core has officially released the leading VMP9000 series test system, which is a modular multi station test system designed for the mass production demand of narrow pulse wafers in Cotai's VCSEL test product line. The product can achieve the minimum drive pulse width of 100 nanoseconds, and the optical power test of more than 300W. It has the complete test capability of LIV, spectral measurement, near-field optical and far-field optical testing under narrow pulses. At the same time, the industry-leading unit hourly capacity (UPH) makes it very suitable for CP testing in the production stage.

"This is a blockbuster product after years of technical accumulation and iteration. It is also a test model that Cotest continues to innovate on the VCSEL test track to launch in line with the actual needs of our customers. When the multi junction high power VCSEL array gradually becomes the mainstream of laser radar, and when domestic optoelectronic semiconductor companies strive to launch leading products, Cotest, as a domestic optoelectronic test equipment company, timely addresses customers' test needs We have launched nanosecond industry-leading equipment to provide the entire industry with high power VCSEL wafer testing capability, which is the mission of Cotest people from beginning to end. VMP9000 will also improve the entire VCSEL test product line of Cotest, enabling us to comprehensively cover the 3D perception test of VCSEL from front to back. " Cotest Optical Core CMO Lu Yuan said.
