A tandem scanning confocal epi-illumination microscope com- prising a light source (1), which may be a laser, for supplying a light beam (2) to a light condenser (18) which. may be a lens. Condenser (18) focuses the light onto object (20) to be examined so as to illumi- nate a point observational field on or within the object. Reflected, flu- orescent or scattered light from the illuminated point field is collected by condenser (18) and transmitted to a returning light receiver (36) which may be in the form of a camera (37) carrying photographic film (38). The outgoing light passing from light source (I) to condenser (18) and the returning light are transmitted via optical fibres and a light se- parator (5) to divert the returning light to receiver (36). The outgoing illuminating light is subjected to scanning movements to scan the ob- ject and the returning light is subjected to similar or tandem scanning movements to scan the photographic film (38). In one embodiment the scanning movements of the illuminating and returning light are pro- vided by two sets of scanning mirrors (16; 17 and 34, 35). In other ar- rangements, tandem scanning may be achieved by a pin hole or slit in a light screen located at an intermediate focal plane.
