The auxiliary imaging unit includes an objective lens, a camera configured to generate an image via the objective lens, a half-silvered mirror disposed between the camera and the objective lens, a light source configured to illuminate a wafer held on a chuck table via the half-silvered mirror and the objective lens, a first polarizing plate disposed between the camera and the half-silvered mirror, and a second polarizing plate disposed between the light source and the half-silvered mirror. The second polarizing plate is disposed such that a polarization plane of light applied from the light source, passed through the second polarizing plate, and reflected by the half-silvered mirror is rotated by a required angle with respect to a polarization axis of the first polarizing plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Laser processing apparatus","description":"A laser processing apparatus includes a main imaging unit configured to image a region to be laser-processed and an auxiliary imaging unit.
