In the military field, micro optics assemblies are used in military optoelectronic systems such as thermal imaging and infrared scanning; in the civilian field, they are used in camera zoom lenses, display systems, medical endoscopes, etc.

Micro Optics Assemblies, also known as optical elements or optical devices, are used to control, adjust, change or transmit light. They are usually made of optical glass, crystal, and other materials. They have specific optical properties, such as refractive index, reflectivity, transmittance, etc., which are key factors in realizing the functions and performance of optical systems.
