Maintain your UV Reflector

The reflector, a crucial component of UV systems, is responsible for 65%-70% of the total UV energy output. However, its coatings may deteriorate over time, resulting in a noticeable decrease in energy output. We often receive questions about when to replace the reflector. To assist you, we’ve outlined two inspections to evaluate the condition of your reflector. 

The easiest way to check if your reflector needs to be replaced is by physically looking at it. Often, contaminants are baked onto the reflector, preventing light from reflecting off of it. If the reflector has lost its overall sheen or seems to have a dull finish, it needs to be replaced. The reflector should be inspected regularly if your production environment contains dust or other contaminants.

A Radiometer is the most dependable tool for measuring the Peak Irradiance (W/cm²) and the UV output’s Energy Density (J/cm²). This ensures that your UV Lamp delivers the correct amount of UV output for your process, providing you with reliable assessments and enabling informed decisions about troubleshooting your lamp’s issues.

Regular measurements of your production line establish a baseline. If the measurements are different from the baseline replacing the reflector could be a solution if you observe a decline in the Peak Irradiance, Energy Density, or both.
