| Why do you exclusively recommend lighting with high-frequency
lamp power supply for the macro exposure stations? | |
| The transmitted-light and reflected-light lightings by Kaiser
Fototechnik GmbH are predominantly equipped with fluorescent lamps. If
these lightings were controlled via an ordinary 50Hz-power supply, the
so called "jitter" and "pump" phenomena would occur
in the LIVE image. These overlaps of 50Hz-power supply and 50Hz-image
scanning of the PAL-TV-norm can only be avoided by the use of high-frequency
power supplies. A much better solution would be, of course, DC-controlled lamps or LED-lightings. But due to matters of cost and construction limitations, this is not yet a solution for Kaiser macro stands. | |
| Which objectives do I use for the best possible
precision of measurements at the macro workstation? | |
| The use of high-quality corrected objectives that are free
of distortions and enable homogeneous projection is a necessity for the
measurement technique. The required resolution depends on the sensor of
the selected camera. With the Macro Objective Kit HR1, that is based on the outstanding Apo-Rodagon objectives by Rodenstock, we offer you broadly applicable high-end optics with more than enough performance reserves for TV cameras and highly resolving digital cameras. In cooperation with our partners, we can offer you the optimum macro optics for each application. | |
| How can I reduce the Minimum Object Distance (MOD)
between objective and measurement object? | |
| There are two basic possibilities. By the use of intermediate rings (C-Mount), you can achieve a much better reduction of the MOD (free of distortions) than by the use of macro ancillary lenses, which are also available for many objectives. For metrological purposes, we advise against macro ancillary lenses. |
