How to detect that the optical path of the vascular stent laser cutting machine has been contaminated?

The cleanliness of the optical path of the vascular stent laser cutting machine directly affects the quality and efficiency of stent cutting, so it must be kept clean. So how to judge whether the optical path is contaminated? Men-luck, a professional vascular stent cutting machine manufacturer, will explain to you in detail.

First of all, before starting the cutting machine every day, check the protective lens to ensure that its cleanliness meets the requirements. You can use the white paper detection method by placing a piece of white paper about 150 to 200 mm away from the nozzle and observing the red light projected onto the paper. If the red light outline is full and clear, with no dark spots or blurry hair, it can be judged that the light path is normal. If the red light has dark spots, blur, or blur, then the light path may be contaminated and needs to be cleaned.

Secondly, the photo paper detection method is used. The detection effect of this method is also very accurate. Place the photo paper approximately 300 mm away from the nozzle and use a laser spot for inspection. If the light spot on the photo paper has dark spots or black spots, or the light spot is not full, then this indicates that there may be contamination in the optical path lens.

If the two methods detect pollution in the optical path, you need to check the collimating protective mirror, center mirror, focusing mirror, collimating mirror and optical fiber to see if there is contamination or damage. Problematic areas need to be cleaned or accessories replaced in time. It is especially important to clean the optical path of the vascular stent cutting machine. It must be ensured that it can be used normally before each startup to ensure the work quality and efficiency of the laser cutting machine.
