We are a manufacturer of image intensifiers, but the shadow enhancement belongs to the vacuum period. After the air leak, the time and material cost of vacuuming and remaking an inner tank are the same, so no manufacturer will repair the inner tank. If the vacuum is forced, it is useless unless the vacuum is higher for the second time.
In addition, the shadow enhancement is not the same as the tube. The ball tube can draw out the air in the oil contained in the core of the ball tube to achieve the purpose of maintenance. However, the inside of the Kagezeng liner is vacuum, and if it is broken, it is broken and cannot be repaired. Customers are advised to buy a new liner.
If you have any problems with your image intensifier, please call Newheek, our professional manufacturer of image intensifiers.
