Inspection device

An inspection device, using to inspect an object, comprising:

• a light source, emitting a plurality of light beams to form a mixed light beam;
• an inspection module, including:
• a first sensing element;
• a shortwave filter, a side of said shortwave filter disposed on a side of said first sensing element correspondingly;
• a beam splitter, a side of said beam filter disposed on an other side of said shortwave filter correspondingly;
• a longwave filter, a side of said longwave filter disposed on an other side of said beam splitter correspondingly;
• and
• a second sensing element, a side of second sensing element disposed on an other side of said longwave filter correspondingly;
• and
• a filter conversion module, including a conversion structure and a plurality of filters, said plurality of filters embedded annularly around said conversion structure, and one of said plurality of filters disposed corresponding to said beam splitter;
• where said mixed light beam is emitted to said object to enable photoluminescence of said object and generating an inspection light beam;
• after said inspection light beam passes through one of said plurality of filters by rotating said conversion structure, said inspection light beam is emitted to said beam splitter;
• said beam splitter splits said inspection light beam to a first split light beam and a second split light beam;
• said first split light beam is emitted to said shortwave filter while said second split light beam is emitted to said longwave filter;
• said shortwave filter filters out the shortwaves of said first split light beam and said filtered first split light beam is emitted to said first sensing element;
• said longwave filter filters out the longwaves of said second split light beam and said filtered second split light beam is emitted to said second sensing element;
• said first sensing element generates a first image signal according to the intensity of said first split light beam;
• and said second sensing element generates a second image signal according to the intensity of said second split light beam.
