Typical Application Areas

Medical and Life Sciences

Medical Endoscopes: As imaging objectives, miniature probes are inserted deep into the human body to acquire high-resolution tissue images. Fluorescence Microscopy: Used for homogenizing the illumination path or acquiring weak fluorescence signals to improve image contrast.
Optical Communication

High-precision microlenses are the core components for achieving efficient, stable, and high-density optical signal transmission. They are primarily responsible for light coupling, collimation, focusing, and channel switching; their precision directly determines the performance and capacity of the entire communication system.
