Title: OPTICAL MEMBER, LIGHT MEASURING DEVICE, SAMPLE HOLDING MEMBER, LIGHT MEASURING SYSTEM AND SPECIFIC WAVELENGTH LIGHT GATHERING MEMBER
Abstract:
The purpose of the present invention is to provide an optical member that is substituted for an expensive optical element such as a notch filter and has a high degree of freedom of shape. A first aspect of the present invention is an optical member that blocks straight traveling of light of a second wavelength rather than straight traveling of light of a first wavelength, and is provided with a silicone resin part, and optical material particles dispersed in the silicone resin part, wherein the refractive indexes of the silicone resin part and the optical material particles match at the first wavelength, and do not match at the second wavelength. Consequently, it becomes possible to provide an optical member or the like that selectively transmit a specific wavelength (the first wavelength) by a member different from those of conventional optical elements.
