Chengdu Paralight Optics Co., Ltd. has remained steadfast in upholding a quality-first philosophy and delivering exceptional customer-centric experiences. Every shipment undergoes rigorous quality control protocols through our meticulously designed inspection system, ensuring optical excellence that consistently surpasses industry standards and fulfills our promise of precision-engineered solutions for global partners.
Ensuring lens quality: CO2 lenses undergo high energy and high temperature in laser cutting processes, so their quality and durability are crucial. Testing can ensure that the lens materials, manufacturing, and coatings meet the quality requirements.
Determining optical performance: The optical performance of CO2 lenses is highly important for cutting and laser transport efficiency and quality. Testing can be used to evaluate optical performance parameters such as transmittance, reflectance, and scatter to ensure the proper functioning of the lens.
Detecting surface conditions: Testing can be used to detect scratches, dirt, or other defects on the lens surface.
