X ray collimator is a device to restrict and restrict X-ray. The radiation emitted by X-ray does great harm to human body, so once the operation is wrong or the relevant parts of the patient are not checked. It can cause unnecessary radiation damage to the human body. So, the lamp of the beam limiter is to simulate the X-ray emission and reduce the waste of radiation and resources. People install analog light source in beam limiter. The lamp of the beam limiter is the earliest halogen lamp. With the development of science and technology, the lamp of beam limiter has been replaced by the shadow-free LED lamp for analog positioning at this stage. Newheek’s three beam limiters, NK102/NK103 and NK202, are LED lights. There is a black wire on the beam limiter to supply power for the LED lamp of the beam limiter. Beam Limiter Lamp.
