| Adaptation at the microscope |
| |
If camera and microscope are perfectly matched to each other, the benefits of digital microscopy become evident. In the following, we will inform you of the major criteria for an ideal digital micrograph.
| Camera adapter / image field |
| |
The size of the intermediate image achieved through the lens system of the microscope cannot be fully covered by a digital image sensor. For example, only 1/8 of the standard 18.0 mm field diameter is imaged on the 8.0 mm image diagonal of a ½” CCD. Therefore, the camera only covers a part of the intermediate image.
This problem can be remedied with a camera adapter (e.g. a C-mount adapter) with image-reducing optics. Such an adapter reduces the image field of the microscope by a set factor (e.g. 0.63x), thus increasing the field of view of the camera. Since more image details are contained on a smaller surface on account of the field extension, the resolution of the digital camera must be selected accordingly. | |
