UV Objektive für CCD-Kameras UV Objectives for CCD Cameras
Bernhard Halle Nachfl. GmbH Objectives for UV Cameras The objectives from this series made of CaF2 and fused silica are optimized for imaging in the deep UV at high aperture ratios. They show a very good UV transmission down to 190 nm and a sufficiently high resolution for imaging on scientific cameras and image intensifiers. The objectives are available with focal lengths of 64 mm, 100 mm and 150 mm. Datasheets with drawings of the lens barrel, additional application notes and data on the imaging quality (incl. MTF tables) are available on request.

The left diagram shows the typical transmission for the UV camera objectives. The transmission is limited by the reflective losses on the uncoated surfaces. Antireflection coatings are available on request. The imaging quality is optimized for the spectral range of 190-450 nm. The right diagram shows the typical variation of the back focal length (s’) referenced to the nominal focal length. To calculate the actual focal shift in length units the values must be multiplied by the nominal focal length of the regarded objective. To use the objectives directly with a camera system a focusing tube and a camera adapter are required which have to be ordered separately. The focusing tubes are specific for the individual focal length. The camera adapters (page 56) are set between the focusing tube and the camera system and can be used for all UV objectives of this series. Extension rings are available to expand the focusing range to shorter object distances (page 56). They have to be set between the focusing tube and the camera adapter. Some extension rings are already included with the focusing tubes and additional ones are only required in exceptional cases. Technical drawings of the focusing tubes, camera adapters and extension rings are available on request. Standard focal lengths and prices Focal length 64 mm The matching focusing tube MUC 2.32.01 is delivered including an extension ring (8 mm) for larger magnifications. order no. price 1 piece price 2-5 pieces price 6-10 pieces [EUR] [EUR] [EUR] OUC 2.32 9485,9011,8501,- MUC 2.32.01 922,905,854,- Focal length 100 mm For this objective two different focusing tubes are available. The model no, MUC 2.51.01 has a thread for quick and convenient focusing. The alternative model no. MUC 2.50.0 is equipped with fine thread for applications requiring very precise focusing. Both tubes are delivered with two extension rings (8 mm and 16 mm) for larger magnifications. order no. price 1 piece price 2-5 pieces price 6-10 pieces [EUR] [EUR] [EUR] Subject to change and correction OUC 2.50 9865,9372,8842,- MUC 2.50.0 795,778,734,- MUC 2.51.01 922,905,854,- 55 Bernhard Halle Nachfl. GmbH Focal length 150 mm The matching focusing tube MUC 3.60.0 is delivered including an extension ring (8 mm) for larger magnifications. The tube allows focusing up to a maximal object distance of about 750 mm ('=-0,25). This objective is not suited for focusing to infinity ('=0). order no. price 1 piece price 2-5 pieces price 6-10 pieces [EUR] [EUR] [EUR] OUC 3.60 11960,11362,10716,- MUC 3.60.0 2050,2009,1896,- Camera adapter for UV objectives To attach the UV objective to available camera systems we offer a line of appropriate adapters which can be used for all our UV camera objectives. The adapters are plates between the focusing tube and the native interface of the camera. camera / mount C-Mount LaVision StreakStar DRS Hadland Imacon 486 PCO Dicam Pro LaVision IRO Roper Scientific PiMax Roper Scientific PiMax3 order no.
