摘要：An optical sensor including a plurality of optical elements such as lenses (23,27),a polarizer (24), an analyzer (26), optical fibres (21,29), and a Pockels element or Faradayelement (25). Light beams from a light source are transmitted through the opticalelements of the optical sensor to optically measure quantitative values acting upon theoptical elements on the basis modulation of the light beams received in a light receiver.The optical sensor includes a first synthetic resin (30) interposed between the opticalelements to be in close contact with the optical elements without any clearance, and asecond synthetic resin (30) of the same material as the first synthetic resin filled aroundthe optical elements. The optical elements may be bonded to a base plate for adjustingoptical axes of the optical elements, and the second synthetic resin may be filled aroundthe optical elements and the base plate.
