The x ray collimator is a device that restrains and limits X-rays. The X-ray emission radiation is very harmful to the human body, so once the operation is wrong or not in the relevant part of the patient. It can cause unnecessary radiation damage to the human body. Therefore, the beam of the x ray collimator is used to simulate the positioning of the X-ray emission, reducing the waste of radiation and resources. People install the analog light source in the x ray collimator. The lamp of the x ray collimator is the first to be applied to the halogen lamp. With the development of technology At this stage, the lamp of the x ray collimator has been replaced by a shadowless LED lamp for analog positioning. Newheek’s three beam limiters NK102/NK103 and NK202 limit beam lights are all LED lights. There is a black wire on the x ray collimator that supplies power to the LEDs in the beam limiter. Limiter light.
