据多方研究表明,近10多年来,美国光学工业基础已处于衰退状态,近半个世纪在光学零件加工工艺方面变化也很小,致使许多市场被外国竞争者夺走。在这种背景下,美国精密光学制造协会和罗切斯特大学光学研究所共同努力,在去年创办了一所光学制 According to various studies, the optical industry base of the United States has been in a recession for nearly 10 years. In the past half century, the change in the processing technology of optical parts has been very small, resulting in many markets being taken away by foreign competitors. Against this background, the American Precision Optical Manufacturing Association and the Institute of Optics of the University of Rochester worked together to create an optical system last year.
