Provided is a microscope that allows irradiation with uniform illumination light without decreasing the amount of light. Employed is a microscope 1 including an incoherent light source 31 that emits incoherent light I; an optical fiber 35 on which the incoherent light I is incident and which guides the incident incoherent light I by repeated total reflection; a DMD 37 having an array of movable micromirrors each reflecting or transmitting the guided incoherent light I; an objective lens 18 that irradiates a specimen 19 with the incoherent light I reflected or transmitted by the DMD 37 and that collects fluorescence F coming from the specimen 19; a dichroic mirror 17 that splits off the collected fluorescence F coming from the specimen 19 from the incoherent light I; and a CCD camera 13 that is disposed at a position conjugate to the position of the DMD 37 and that detects the fluorescence F coming from the specimen 19 and split off by the dichroic mirror 17.

An object to be achieved by the invention is to provide a biodegradable low-charging fiber. The prevent inventors have found that when a specific amount of a specific phospholipid that is not known to have antistatic properties is added to a biodegradable polymer, and the resulting mixture is formed into a fiber having a smooth surface, low-charging properties are developed. The invention has thus been accomplished. The invention is a fiber having an average surface porosity of less than 3% and made of a biodegradable polymer that contains a specific amount of a specific phospholipid.
