ABSTRACT:
In a joined optical member, let the adhesion strength between a surface coating layer and an eyepiece prism be A1, the adhesion strength between the surface coating layer and a deflector prism be A2, the adhesion strength between the surface coating layer and adhesive be A3, and the adhesion strength between, at one end, the adhesive and, at the other, the eyepiece prism and the deflector prism be A4, then A1(A2)>A3and simultaneously A4>A3. This makes removal of superfluous adhesive on the surface coating layer easy, and prevents scratches on the exterior surfaces. Even after removal of superfluous adhesive, the surface coating layer remains on the exterior surfaces of the eyepiece prism and the deflector prism. This prevents scratches on the exterior surfaces in actual use, and prevents degradation of optical performance.
