A n optical inspection instrument comprising a housing (11), a mirror (12) mounted obliquely relative to the axis of the housing (11) for reflecting the image of an illuminated object (13) to an observer who is holding the instrument, and a light bulb (17) arranged adjacent a cut-out (16) in the wall of the housing (11) so as to emit light transversely of the axis of the housing (11) to illuminate the object (13) directly without the light first undergoing reflection from the surface of the mirror (12). The instrument may be used in medicine or dentistry, or may have veterinary use or use in industry generally for inspection or examination purposes. |
