Advanced probe and measurement systems targeting Micro Display applications


VEGA Series

High performance Laser Diode probe & test solutions


GEMINI Series Overview

Micro LED (µLED) is a disruptive optical technology breakthrough in the display industry. Micro LED displays offer tremendous potential for consumer/ display/ automotive applications because they are brighter, faster, and longer life compared with other emissive devices.

With years of experience and customer interactions gained in Optoelectronic devices testing, MPI introduces the GEMINI series wafer probers to provide fast, efficient, and precise measurement to help you tackle the Micro LED test and measurement challenges.
