Microscope. An optical (light) microscope with various laboratory equipment. The equipment consists of instruments used for light microscopy such as scissors, scalpel, pipette and microscope slides. The microscope (at centre right) has a black tubular chamber with the eyepiece at top and three objective lenses (silver) at bottom. Below this is the specimen table with a mirror below to reflect light upwards, back to the specimen and eyepiece. Focus is adjusted using the circular silver knob (at upper right) which moves the lens unit up and down. Objects are magnified by the combination of eyepiece and objective lenses.
