The present invention relates to optical apparatus. In particular it relates to optical apparatus having utility in medical procedures, more particularly dental procedures and especially disinfection procedures. In particular, we describe an optical apparatus comprising a handpiece (10) housing a light emitting diode light source (21) and a light delivery system comprising a light guide (14) having a proximal end mountable to the light delivery system to receive light from the light source (21) and a distal end (15) from which light is emitted from the apparatus. Preferably, the light- emitting diode light source (21) is a single light- emitting diode and preferably the handpiece comprises cooling means (23, 24, 25) adapted to cool the light- emitting diode light-source (21).
