• Packaging and Shipping

I. Raw Material Procurement

1. Optical glass

• As one of the core materials of infrared lenses, the selection of optical glass is crucial. We strictly screen according to standards such as high transmittance, low scattering, and good thermal stability. Usually, we will choose special infrared optical glass such as germanium glass and silicon glass. These glasses can effectively transmit light in the infrared band and have high hardness and corrosion resistance.

• In terms of supplier selection, we will conduct sufficient market research, refer to the recommendations of other manufacturers, and conduct on-site inspections of the supplier's production facilities and quality management system. We only choose suppliers with good reputation, stable quality, and timely supply capacity to ensure the quality and supply stability of raw materials.

2. Coating materials

• Coating materials are one of the key factors to improve the performance of infrared lenses. We will choose appropriate coating materials according to different application needs, such as magnesium fluoride and silicon dioxide. These materials can form a good antireflection coating in a specific infrared band, improving the transmittance of the lens and reducing reflection.

• For the quality control of coating materials, we will be strict. When purchasing coating materials, we ensure that indicators such as purity, particle size distribution, and stability meet the requirements. At the same time, we will strictly review suppliers to ensure that their production processes meet the requirements of the quality management system.

3. Mechanical parts

• Mechanical parts such as structural parts and fasteners of infrared lenses also need to have high precision, high strength, and good corrosion resistance. We usually choose materials such as aluminum alloy and stainless steel for processing and manufacturing.

• In the process of part procurement, we will strictly screen and review suppliers to ensure that the size, precision, and surface quality of the parts they provide meet the requirements. For unqualified parts, we will require suppliers to rework or replace them.

II. Production and Processing Process

1. Optical processing

• Cutting and grinding: Cut and grind the purchased optical glass according to the design requirements to make it reach the required shape and size. We have high-precision cutting equipment and grinding machines to ensure the surface quality and precision of optical glass.

• Polishing: Polish the ground optical glass to improve its surface finish and transmittance. Our polishing process uses special polishing agents and polishing equipment, and strictly controls the polishing time and pressure to avoid scratches and deformation.

2. Coating

• Cleaning: Before coating, we will thoroughly clean the optical glass to remove surface impurities and oil stains. The cleaning process uses methods such as ultrasonic cleaning machines and solvent cleaning to ensure that the surface of the optical glass is clean and dust-free.

• Coating process: We use advanced physical vapor deposition (PVD) or chemical vapor deposition (CVD) methods to form a coating on the surface of optical glass. During the coating process, we will strictly control parameters such as temperature, pressure, and gas flow to ensure the quality and uniformity of the coating.

3. Assembly

• Part inspection: Strictly inspect the purchased mechanical parts to ensure that their size, precision, and surface quality meet the requirements. Unqualified parts will be returned to the supplier for rework or replacement in a timely manner.

• Assembly process: Assemble the optical glass and mechanical parts according to the design requirements. We have professional assembly tools and equipment and strictly control the assembly sequence and force to ensure the performance and stability of the lens.

III. Quality Inspection

1. Optical performance inspection

• Transmittance test: Use equipment such as infrared spectrophotometers to test the transmittance of the lens to ensure that its transmittance in the infrared band meets the design requirements.

• Resolution test: Use equipment such as resolution test cards to test the resolution of the lens to ensure that it can image clearly.

2. Mechanical performance inspection

• Sealing test: Conduct a sealing test on the lens to ensure that it can work normally in harsh environments.

• Shock resistance test: Conduct a shock resistance test on the lens to ensure that it will not be damaged when subjected to vibration and impact.

IV. Packaging and Shipping

1. Packaging

• Protective measures: To prevent damage during transportation and storage, we will carefully package the produced infrared lenses. Packaging materials such as foam plastics and cartons are selected, and desiccants and other protective measures are added inside the packaging.

• Labeling: Mark information such as the model, specification, and production date of the lens on the packaging for easy identification and management.

2. Shipping

• Inspection: Before shipping, we will conduct a final inspection on the packaged lens to ensure that its quality meets the requirements.

• Transportation: Choose an appropriate transportation method to ensure that the lens can be delivered to customers safely and timely.

In conclusion, in the production process of infrared lenses, we always adhere to strict quality control and the production concept of continuous improvement. From raw material procurement to production processing, quality inspection, and packaging and shipping, every link is carefully planned and strictly implemented to ensure that we provide high-quality infrared lens products to customers.
