This clip is about the development and history of microscopes. It begins with a blurry CU of bacteria organisms. Another CU of bacteria that has multiple colors because of the light refracted through the glass created a color spectrum. A CU of a new model of microscope with with two types of glass in each lens to cancel out each other’s color dispersion. Cuts to a view through a microscope with an incorrectly ground lens. A shot of a microscope built in 1829. A CU of a hands putting lenses on a metal sphere as part of the process of modern lens making. A WS of machines spinning the spheres within pots of fine abrasives. A CU of one of the pots. A MS of a man testing each lens against a perfect lens. Shot of of lenses being placed on the objective of the microscope. A CU of a man looking through a microscope. The man puts the microscope pieces together. A CU of wood cells and bone cells.
