Today, the 22nd intellectual property day with the theme of "Intellectual Property and Youth: Innovation, Building the Future" has come as promised. Each year's Intellectual Property Day provides us with a unique opportunity to let people in all regions of the world use their creativity and intelligence to promote change, drive technological innovation and open up a path to a better future.

On this road, the Cotest people have always kept thinking and making progress with their own curiosity and creativity.

As a leading supplier of optoelectronic semiconductor testing equipment in China, Cotest Optical Core Corporation has obtained a total of 40 core invention patents and related software copyrights, taking the lead in opening up the core link of optoelectronic device testing, including three types of longitudinal testing requirements: electrical LIV, near-field optical analysis, and far-field optical analysis; And four kinds of horizontal conditions, such as extremely narrow pulse, temperature control, calibration and production line automation. The three verticals and four horizontals can be modularized, forming the main technical core and flexible rapid development capability of Cotest.
