Preventing Laser Condensation in Summer

Preventing Laser Condensation in Summer

Introduction: The Challenge of Summer

With the arrival of summer in May and the noticeable increase in temperature, we are in the midst of early summer. Although it's not yet the time of scorching sun and unbearable heat, there is an increase in thunderstorm weather and high humidity. Frequent rainfall and a damp environment can easily lead to internal condensation in lasers. So, how can we prevent condensation in lasers?

Tips for Preventing Laser Condensation

1. Operation and Environmental Requirements

Although fiber optic transmission cables of lasers can be used in harsh environments, lasers have high requirements for the operating environment.

If the value at the intersection of the laser's environmental temperature (air-conditioned room temperature) and the relative humidity of the laser environment (relative humidity of the air-conditioned room) is less than 22, there will be no condensation inside the laser. If it's above 22, there's a risk of internal condensation in the laser.

You can improve the situation by lowering the laser's environmental temperature and relative humidity. Or set up the air conditioning cooling and dehumidification functions, maintaining the environmental temperature of the laser not exceeding 26 degrees, and keeping the relative humidity below 60%.

We suggest customers to monitor and record temperature and humidity regularly to identify problems in time and prevent risks.

2. Avoid Frosting

It's important to avoid internal and external frosting of lasers that do not come with their own air conditioning.

If a laser without built-in air conditioning is used in the work environment, once the cooling temperature drops below the dew point temperature of the laser's internal environment, moisture will precipitate onto the electrical and optical modules. If no measures are taken at this time, the surface of the laser will start to condense. So, if you see frosting on the shell of the laser, it means that condensation has occurred inside. You must stop work immediately and improve the laser's working environment right away.

3. Laser Cooling Water Requirements

The cooling water for the laser must be set above the dew point temperature in the most severe operating environment.

4. Avoid Condensation in the Processing Head Environment

When the seasons change or when there is a large change in weather temperature, if abnormal processing occurs in the laser, in addition to the machine itself, it's necessary to check whether condensation has occurred in the processing head environment. Condensation in the processing head can cause serious damage to the optical lens:

1. If the cooling temperature is lower than the environmental dew point temperature, it will cause condensation on the inner wall and optical lens of the processing head.

2. Using auxiliary gas lower than the environmental dew point temperature will cause the optical lens to condense quickly. It is recommended to add a booster between the gas source and the processing head to bring the gas temperature closer to the environmental temperature and reduce the risk of condensation.

Conclusion: Prioritize Proper Maintenance

Keeping these points in mind can help prevent laser condensation in the summer and ensure optimal performance of your equipment. Regular monitoring and necessary adjustments to the environment can protect your investment and prolong the life of your lasers.
