Strahlreduzierer
| Der 4X-Strahlreduzierer ist ein Bilderfassungssystem, mit dem die Ebene 30cm vor dem Strahlreduzierer auf dem CCD der Kamera abgebildet wird. Dabei wird das Bild um den Faktor 4 verkleinert und gleichzeitig invertiert. Der Strahlreduzierer wird mit den drei schraubbaren Abschwächern der Kamera bestückt. Da die Intensität des Strahls durch die Fokussierung um das 16(4x4)-fache erhöht wird, ist es ratsam solch einen Strahl stärker abzuschwächen, als einen unfokussierten Strahl. Verwenden Sie dazu optional erhältliche externe Strahlteiler und Abschwächer (siehe Bestellinformationen für Zubehör). |

| 4X reimaging beam reducer | Screw on beam reducer for beams in the wavelength region 360 - 1100nm that reimages the beam 30cm in front of the unit onto the CCD while reducing the beam size 4X. Entrance aperture is 50mm. Fits 4.5mm recess cameras only | SPZ17017 | ||
| Accessories | ||||
| Filter holder and 50x50 filter set for 4X beam reducer | Filter holder with set of 4 standard Schott 50X50mm neutral density filters. Useful to further reduce intensity after beam splitter before inputting into 4X beam reducer. Mounts to standard ¼" thread, ½" diameter laboratory rod. | SPZ08240 | ||
| LBS-100 to 4X beam reducer adapter | This adapter enables mounting of the LBS-100 beam splitter / attenuator assembly in front of the 4X beam reducer. The combined assembly can image large high power beams in one unit. See illustration on page 163. | SPZ17029 | ||
