A polygonally shaped carbon nanotube (CNT) sheet optical bellows providing enhanced stray light suppression, the polygonally shaped CNT sheet optical bellows includes: a free-standing non-woven CNT sheet; a polymer bonded to the non-woven CNT sheet; and an elastomer film bonded to the polymer film, creating a laminate film, the laminate film being rolled to form a cylinder by applying an adhesive along a bonding edge of the laminate film to adhere the bonding edge to an opposite edge of the laminate film, an outer side of the laminate film comprising diamond-shaped elements, the diamond-shaped elements being pinched, pressed, folded and collapsed in a rotating manner around a circumference of the cylinder, creating the polygonally shaped CNT sheet optical bellows.
