First surface mirrors, also known as front surface mirrors or FSM, provide a true reflection with no ghosting effect. Regular mirrors have an aluminum mirror coating on the backside of the glass that creates a faint secondary reflection. Glass first surface mirrors solve ghosting by having the mirror coating on the face of the glass, which maximizes the amount of light reflected and minimizes distortion.
