    • An optical element which includes an optical block having a cavity part formed on an optical path and an inclined face formed in an internal face of the cavity part at a prescribed inclining angle with respect to a traveling direction of light. Multilayer films of the same structure are formed at least on the internal face of the cavity part and on an interface between a light incident end and/or emission end of the optical block and outside. The multilayer film formed on the incline face in the internal face of the cavity part has at least a wavelength selecting function for light to be used.
    • 一种光学元件,包括具有形成在光路上的空腔部分的光学块和相对于光的行进方向以规定的倾斜角度形成在所述空腔部分的内表面中的倾斜面。 至少在空腔部分的内表面和光学块的光入射端和/或发射端与外部之间的界面上形成相同结构的多层膜。 形成在空腔部的内表面的倾斜面上的多层膜至少具有用于光的波长选择功能。

    • There is provided an optical element which can achieve more reduction in the number of components, downsizing, low cost, and an improvement in the mass-productivity while maintaining an excellent optical property. The optical element comprises: an optical block having a cavity part formed on an optical path and an inclined face formed in an internal face of the cavity part at a prescribed inclining angle with respect to a traveling direction of light, wherein multilayer films of the same structure are formed at least on the internal face of the cavity part and on an interface between light incident end and/or emission end of the optical block and outside. The multilayer film formed on the inclined face in the internal face of the cavity part has at least a wavelength selecting function for light to be used, and the multilayer film formed on other face than the inclined face has an antireflective function for light to be used.
