Self-Illuminating Optical Alignment Target
Optoelectronic instrument designed for use as self-illuminating optical alignment target. Called "fiber-optic remote target" (FORT), instrument facilitates and accelerates optical alignment by providing small, bright reference spot of light easily visible, without having to supply illumination from external source, without concern for shadowing, and without need for antiglare adjustments.
