The ZM-87 Portable Laser Disturber is a Chinese electro-optic countermeasure neodymium laser device. The ZM-87 was primarily intended to blind humans but was also reported to damage the photo-electric elements in laser rangefinders, videocameras and missile seekers. Roughly twenty-two of the devices were produced by the company Norinco before production ceased in 2000 as a result of the 1995 United Nations Protocol on Blinding Laser Weapons ban.
