Abstract
OTHER workers (Wilson1 and Doncaster2) have discussed methods of incorporating electronic flash in microscopy; but both of them exposed the tube and no attempt was made to limit and concentrate the light from the flash tube on to the microscope mirror. A large amount of light is lost in this way, and Doncaster2 noted that with high powers (4-mm. objective) of the microscope, high-speed film had to be used with the consequent disadvantage of large grain. In the method to be described, the electronic flash as illuminant is incorporated in an optical bench and an attempt has been made to concentrate the flash on to the microscope mirror so that fairly critical illumination is attained.
