FAQ: I use an LM digital adapter with a C-mount connection on a microscope with a phototube and C-mount port connection with a factor of 0.5x (or 0.3x or 0.63x). Despite exhaustive experimentation I am unable to produce a well-illuminated image. The result is always a small circular picture with a black outline.
All LM digital adapters are designed to work with a phototube equipped with a C-mount connection and a factor of 1x. If a different C-mount connection (factors 0.3x to 0.7x) is used, the camera sensor will not be optimally illuminated.
The circular image will have a black border. The lower the factor, the smaller the circular image will be. This peripheral darkening is known as vignetting and should be avoided. Vignetting means that the sensor chip is not fully utilised, and this leads to a reduction in the quality of the image.
We offer a C-mount connection with a factor of 1x for a large number of microscopes.
