用激光检查装药的玻璃瓶可知道容器本身是否抽成了真空。这项技术是Benthos公司制造检验设备的人研究的。以前对容器的真空度只进行抽样检验(典型检验只占每批产品的0.1%)。用激光则可100%的检验。工作原理是这样的,当激光束通过瓶子时,瓶中的气压越低,吸收激光就越少;在传送

A glass bottle with a laser-checked charge shows if the container itself is evacuated. The technology is being researched by Benthos to make inspection equipment. Previously, only the vacuum of the container was sampled (the typical test only accounted for 0.1% of each batch of product). With the laser can be 100% inspection. The working principle is such that as the laser beam passes through the bottle, the lower the pressure in the bottle, the less the laser is absorbed;
