| 摘要 |
The invention concerns a system for achieving an optical image of an object ( 136 ), and/or for achieving optical collimation ( 137 ) of light from a light source ( 130 ), comprising a concave mirror ( 131: 134 ), the surface normal of which forms an angle with the incident light in a beam. A negative lens ( 132, 133 ) that co-operates with the concave mirror is arranged in the incident and/or exit beam paths such that an image with eliminated or reduced imaging aberrations is achieved in a focal plane ( 135 ), and/or that the exit light from a light sources ( 130 ) is collimated ( 137 ). |
