It was 1950 when Mr. Hopkins met Dr. Hugh Gainsborough, a gatroentreroligst at St. George’s Hospital London, where he was put forth with a challenge of illumination while operating within abdomen.  By 1954, Hopkins invented flexible glass rods which transmitted light from external light source to the inspecting tissue residing within the body of patient, which came to be known as rod lens system.  Concurrently early 1950 saw the birth of fibre optic light transmitting system which revolutionized the field of communication.
