| 摘要 |
<p>The invention relates to a collimator device (1) for testing and adjusting at least one optical device (9), in at least one useful wavelength range, by means of at least one test pattern (2), comprising: - a housing (3), which at least approximately absorbs radiation in the at least one useful wavelength range, and which has at least one region (4, 5) that is at least partially transparent to radiation in the useful wavelength range, at least one at least partially transparent region (5) having the test pattern (2), and at least one at least partially transparent region being an entrance region (4),  - at least one collimator element (6) for producing a parallel beam course, and - an optical beam path (7) that, via the collimator element (6), images the at least one test pattern (2) virtually into infinity, through an entrance region (4), a contrast of the at least one test pattern (2) being produced by a radiation in the at least one useful wavelength range that is present outside of the housing (3).</p> |
