Publication number: 20170205608Abstract: An optical lens comprising a first lens (L1), a second lens (L2), a third lens (L3), a fourth lens (L4), and a fifth lens (L5) that are sequentially arranged on a common optical axis in the transmission direction of an incident light. Both the first lens (L1) and the fifth lens (L5) are negative meniscus lenses. Both the second lens (L2) and the third lens (L3) are positive meniscus lenses. The fourth lens (L4) is a biconvex lens. The optical lens is applicable in an optical system of a laser processing apparatus. When an employed processing wavelength is different from a monitoring wavelength, imaging color differences in a monitoring system can thus be eliminated, specifically, when a wavelength in the infrared range is employed as a laser processing wavelength while a red wavelength serves as the monitoring wavelength, improved imaging effects are provided in the monitoring system, thus ensuring the quality of laser processing.Type: ApplicationFiled: August 29, 2014Publication date: July 20, 2017Inventors: Jiaying LI, Chaoming ZHOU, Bo SUN, Yuqing CHEN, Yunfeng GAO
