High Resolution Image Inverters

A fiber optic inverter (twister) inverts an image from its input surface to its output surface. Fiber optic inverters are used primarily in night vision image intensifier tubes. The objective lens of the night vision device inverts the primary image while the fiber optic Inverter turns this image right side up and provides a compact intensifier package.

SCHOTT’s Inverters are fabricated to customer-specific requirements. Customized inverters utilized in night vision technology (i.e. Night Vision Devices utilize fiber optic Inverters within intensifier tubes).

Fiber optic image inverters are used primarily in night vision image intensifier tubes, but these imaging components can be sued in any application that requires the correction of an inverted image, while also providing a compact, vacuum tight and rugged package. Fiber optic inverters are manufactured using fiber elements ranging in size from 4 to 25μm that are fused together into a coherent imaging array, which is then heated and twisted to invert the image 180 degrees.
