A concentrating optical system in which semiparabolic type mirrors being spread to one side are constructed for use with primary concentrating and secondary concentrating, or a concentrating system for concentrating in parallel a large and small parabolic type mirrors (21, 22) confronting each other is constructed, so that the parallel concentrated light is heat collected, light collected or utilized for lighting, or else a refractive type converging concentrator is constructed whereby concentrating at high concentrating ratio. Since a light of wide range from not only high density but up to low density is tracked and concentrated, not only a solar furnace (50) but even telescope also are newly developed. A wide range concentrated light utilizing device is made in which not only natural light such as sun light and star light but also the light produced from artificial light source can be concentrated whereby utilized to industry. |
