摘要：
An illumination apparatus includes a through-hole for detection formed at a center portion, and irradiates diffused light and directional light to an object to be detected. The apparatus includes an annular diffusion plate which diffuses light, a light source disposed annularly, and an annular reflection plate which reflects light from the light source to the side of said object to be detected. The diffusion plate, light source, and reflection plate are disposed in the order from the side of said object to be detected. The diffused light is generated by irradiating light from said light source to the object to be detected through said diffusion plate. Light from said light source is reflected by said reflection plate and then irradiated to the object to be detected.
