고출력 355nm 자외선 레이저 절단 렌즈를 선택하는 방법은 무엇입니까?

레이저 절단기의 마모 부품에는 여러 종류가 있습니다. 오늘은 주로 레이저 절단기의 보호렌즈를 소개해드리겠습니다.

이름에서 알 수 있듯이 보호 렌즈는 먼지와 슬래그 비말이 포커싱 렌즈를 손상시키는 것을 방지하는 데 사용됩니다. 레이저 커팅 머신에 사용되는 것 외에도 레이저 마킹, 레이저 용접 및 레이저 조각 등 다른 레이저 장비에도 필요합니다. 보호 렌즈의 응용 시장이 매우 크다는 것을 알 수 있습니다.

시중에 나와있는 보호 렌즈의 가격은 수십 위안에서 수백 위안에 이르기까지 매우 다양하며 품질도 다릅니다. 물론 조악한 렌즈는 드문 일이 아닙니다. 렌즈를 제대로 선택하지 않으면 큰 레이저 손실, 보호 렌즈의 빈번한 손상, 불안정한 제품 품질 및 기업에 심각한 손실을 초래합니다. 따라서 올바른 보호 렌즈를 선택하는 것이 매우 중요합니다.

레이저 절단기의 보호 렌즈를 선택하는 세 단계:

1) 일치하는 차원, 이것은 이해하기 쉽습니다.

2) Material, according to different laser power, considering the cost of use, you can choose K9, quartz. In the actual application process, professional manufacturers divide these two types of materials into multiple grades, and customers can choose the corresponding specifications according to actual needs.

3) Coating, laser anti-reflection coating, different coating technical parameters are adopted according to the use environment.

Although the protective lens of the laser cutting machine is a vulnerable part, in order to improve its utilization rate and reduce production costs, the protective lens can be cleaned regularly to achieve the purpose of reuse. The following are the three cleaning steps summarized by the high-energy laser:

1. The protective lens material is ZnSe (arsenic zinc), which is brittle and afraid of falling; pay attention to when disassembling: do not use too much force or collide with hard objects. There is an antireflection film on the surface, which is afraid of pollution, humidity, oiliness, and scratching; therefore, it is required to provide dry and degreasing air during work. Do not directly handle the laser cutting machine to protect the lens of the lens, because the skin is oily Will cause permanent damage to the lens surface. On the contrary, you can wear gloves and its special set for operation. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the protective lens of the laser cutting machine, it can only be clamped along the non-optical surface, such as the frosted edge of the mirror plaque.

2. Under normal circumstances, it is necessary to check the condition of the laser cutting machine to protect the lens before use and before and after cleaning. Because most contaminants and surface defects are relatively small in size, we often need to use magnifying equipment when inspecting lenses. In addition to magnifying equipment, sometimes we also need to illuminate the optical surface with a relatively bright light to enhance the specular reflection intensity of surface contaminants and defects, so that contaminants and defects can be found more easily.

3. When cleaning a laser cutting machine to protect the lens, always use clean wipes and optical grade solvents to prevent damage by other contaminants. The wipe paper must be moistened with a suitable solvent, and it must not be used dry. In consideration of softness, the usable wipes are pure cotton Webril wipes or applicators such as cotton balls, lens tissues, and cotton swabs.
