| 摘要 |
The present invention relates to a device for determining the shape of the wave surface transmitted by a substantially parallel-faced transparent component (P), which includes a support (S) for the component (P), an interferometer (I), means for moving the support (S), and a control unit which determines, from the measurements by the interferometer (I), the shape of said wave surface. According to the invention, the support (S) is made in such a way as to let the light beam (FM) emitted by the interferometer (I) and transmitted by the component (P), which is transparent, pass through it, and said device includes a swivelling mirror (M1) arranged approximately orthogonally to the beam (FM) transmitted by the component and oriented in such a way as to send said beam (FM) back in the emission direction (D1).
