Incandescent lamps are the most common type of light source.  Typical incandescent lamps emit light by heating the filament and the emitted light continues broadband spectrum, which can be described by black body radiation. \\ Incandescent lamps are the most common type of light source.  Typical incandescent lamps emit light by heating the filament and the emitted light continues broadband spectrum, which can be described by black body radiation. \\

The light sources and detectors used in optical instruments are potential sources of hazards to human if not properly operated.  These hazards primarily come from the optical radiation, high voltage electrical devices, and chemicals.  The light sources and detectors used in optical instruments are potential sources of hazards to human if not properly operated.  These hazards primarily come from the optical radiation, high voltage electrical devices, and chemicals.
