The Production Workshop of Microlens Array

The production workshop of microlens arrays is a manufacturing workshop with high accuracy requirements. A microlens array is a micro-optical element composed of many tiny lenses, which can be used in optical imaging, optical communication, optical sensing, and other fields. The main equipment in the microlens array production workshop includes a laser direct writing machine, lithography machines,etching machines, photoresist spin-coating machine,  vacuum coating equipment, and optical measuring instruments, etc. During the production, it is necessary to carry out processes such as photolithography, etching, coating, and inspection, and use high-precision and stable instruments and equipment to ensure the high-precision and high-quality of microlens arrays.

The production process of the microlens array production workshop includes multiple steps such as photolithography, etching, coating, and inspection.

Among them, photolithography is a key step in manufacturing a microlens array. Etching is the etching of patterns deposited on a thin film substrate to form the lens structure of the microlens array. The above steps require the use of a photoresist and a lithography machine. The following picture shows an operator in a production workshop using a lithography machine to perform contact lithography on a microlens array.

Coating is another important step that requires the use of a Vacuum Deposition System. The following picture shows the operating staff in the production workshop using a vacuum coating machine to coat the microlens array.

The inspection steps require the use of equipment such as a microscope, profilometer, and micrometer. The following picture shows the operating staff in the production workshop using a microscope to perform quality testing on the microlens array.

The production process in the microlens array production workshop requires a high degree of accuracy and stability to ensure the high quality and performance of the microlens array.
