ABSTRACT:
An optical head is disclosed which comprises a light source such as a diode laser and an optical element, for example, a collimating lens. The collimating lens and the diode laser are mounted along a common optical axis. A thermoelectric cooling element is provided in the head to control the temperature of the diode laser. In order to precisely locate the collimating lens relative to the diode laser, the housing of the collimating lens is mounted directly onto the barrel of the diode laser.
