L-04 Laser Diode Lighter



    The lighter is intended for on-line testing of serviceability and for checking temporal parameters of image converter cameras of pico-, nano, -micro- and millisecond ranges. With the aid of the lighter the illumination of slit and frame test-objects as well as slits and a frame field of image converter cameras can be performed in continuous and pulse modes of operation.
     The main components of the lighter:

     The lighter consists of two parts: a control unit and a radiator. A laser diode serves as is a radiating element of the lighter.


     Principle of operation:

    The control unit provides a constant or pulse current through a radiator. The radiator represents the laser diode fixed in a tube, located on a support with changeable height. In the tube there is a lens with an aperture ~ 18 mm and a focal length ~ 15 mm. A distance from the lens to the laser diode can be adjusted. As a result, a radiation flux can be set divergent, quasi-parallel or convergent.
