<P>PROBLEM TO BE SOLVED: To provide a wide angle light detection member able to widen a capture angle while maintaining a narrow diameter, prevent decrease in capture angle even if a liquid adheres to its leading end, furthermore, facilitate its assembly, and be suitable for a scan type observation device, and to provide a scan type observation device using the same. <P>SOLUTION: The wide-angle light detection member has: a detecting optical fiber 1 configured to receive light; a capture angle widening surface 4 provided at the leading end of a detecting optical fiber 1 and configured to widen a capture angle; and sealing means 5 having a refraction index different from an optical element located near behind the capture angle widening surface 4 and configured to seal the capture angle widening surface 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
