Manual collimators are mainly used for X-ray machine photography. By manually adjusting the knob or lever on the collimator, the opening and closing activities of the guide vane covered by the collimator can be realized.
In addition to the above internal structure, there is also an irradiation field indicating system. The manual collimator uses the focal point of the indicator bulb to simulate the X-ray tube, replaces the X-ray with visible light, and reflects it on the bed or film frame through a mirror. The path of the reflected visible light is the same as the path of the X-ray beam passing through the mirror, so the size of the field can be indicated in advance. Due to the short service life of the indicator light, the light is controlled by a button switch and can be automatically turned off within 15s~1min. Some indicators have two brightness levels in their lifespan, in order to meet the requirements of the indoor brightness to display the field indicator.
Some manual collimators are marked with the size of the exposure area, and have a corresponding focal length around the knob or within the range of the lever. They are mainly used to set the exposure area before the light is turned on. Therefore, the size of the exposure area indicator light is on It can be adjusted quickly and can extend the life of the indicator light.
