Fiber Optic Inverter Fiber optic inverter can be used in the image inversion system. It makes the input image inversion 180?/font> in output surface. Fiber optic inverter can replace the optic lens system in the low light level night vision instrument and can greatly reduce the size, weight and cost of image intensifiers and miniaturizes the night vision devices. In the same time, fiber optic inverter has the good property of resolution and clear image transmission. It has been widely used in all devices requiring image inversion.
