The microscope became the focus of many scientists, and opticians as they worked towards modifying the instrument to fit the needs of the professionalizing academic class. However, the microscope was also becoming more accessible to the public. As manufacturers worked to widen their customer base, they adapted their designs to be affordable, and simple to use for public use. The growth of science societies throughout Britain, and America created an environment in which the microscope could further develop. The establishment of societies allowed for collaboration between members, as they promoted their own studies through publications, lecturers, and clinical studies. Microscope societies appeared, such as the Royal Microscopical Society (1839) and Quekett Microscopical Club (1865.)  These societies dedicated themselves to the development of the microscope, and expanding its accessibility to the public. They published manuals for the microscope outlining how the instrument functioned, which allowed those not in educational institutions to develop their own skills, and interest for the instrument. These manuals also included how the lens work, as well as the many theories attached to its function.
