The optical instrument industry does have strict requirements for temperature, humidity and cleanliness.
The optical instrument industry does have strict requirements for temperature, humidity and cleanliness. These requirements are mainly due to the high precision of optical instruments and their sensitivity to the production environment. The following is a detailed description of these requirements:
1. Temperature and humidity requirements
The optical instrument industry has specific requirements for the temperature and humidity of the production environment to ensure the accuracy and stability of the product.
Temperature: Generally required to be between 20℃~25℃, but the specific value may vary depending on the product type and production process. For example, some data indicate that the optical instrument assembly environment requires a stable temperature, generally required to be within the range of 20℃±2℃; while the optoelectronic optical product clean workshop requires a temperature of 24±2℃.
Humidity: Usually required to be between 40%~60%RH, the specific value may also be adjusted depending on the product type and production process. For example, the optical instrument assembly environment requires a humidity range of 50%RH±10%RH; while the optoelectronic optical product clean workshop requires a relative humidity of 55%+5%.
2. Cleanliness requirements
Optical instruments also have high requirements for the cleanliness of the production environment to avoid the impact of pollutants such as dust and particulate matter on product quality.
Cleanliness level: The cleanliness level of a clean room is usually measured by the number of dust particles (dust concentration) contained in a unit volume of air. Optical instrument production usually needs to be carried out in an environment with a cleanliness level of 1,000, 10,000 or 100,000.
Air filtration: In order to ensure cleanliness, optical instrument production workshops usually use high-efficiency air filtration systems to remove dust and particles in the air.
Prevent static electricity: Since optical components are sensitive to static electricity, anti-static measures are also required, such as installing anti-static floors and wearing anti-static clothing.
3. Control measures
In order to meet the requirements of the optical instrument industry for temperature, humidity and cleanliness, the following control measures are usually required:
Install precise temperature and humidity control equipment: These devices can monitor and adjust the temperature and humidity in the production environment in real time to ensure that it is in a stable state.
Use an efficient filtration system: The filtration system can effectively remove dust and particles in the air and reduce their impact on optical components.
Regular maintenance and inspection: Regularly maintain and inspect the equipment in the production environment to ensure its normal operation and avoid the impact of temperature and humidity fluctuations and pollution on production.
Control personnel access: Reduce the entry of dust and pollutants by restricting personnel access, wearing clean clothes, setting up air showers, etc.
In summary, the optical instrument industry has strict requirements on temperature, humidity and cleanliness, which are crucial to ensuring the accuracy, stability and reliability of products.
