The LM Pro microscope camera adapters: achieving better image quality with an optimised aperture configuration

Adapter solution with integrated aperture diaphragm: maximum flexibility and professionalism with the LM wide field adapters

Depending on the microscope, an additional aperture diaphragm in the adapter unit can help achieve consistently better image quality. As a rule, a microscope is equipped with many different aperture diaphragms to get the best possible image quality and field of view. In laboratory microscopes, each individual objective lens has its own aperture diaphragm. Lower-priced stereo microscopes with zoom lenses usually come with a fixed aperture diaphragm. More expensive stereo microscopes and macroscopes have a variable iris diaphragm in the stand base, which can be adjusted to any given application.

To add even more flexibility, our adapter solutions offer the option of optimising the aperture configuration of the adapter.

We can deliver our LM wide field adapters with four aperture diaphragms, each featuring a different aperture diameter: 

Especially in older and cheaper microscopes, image flaws may occur, which can be corrected by aperture size. With smaller apertures, less light is recorded and the depth of field is greater. Since the ideal aperture diameter is different for each microscope, we offer four diaphragm versions with diameters between 2 mm and 6 mm. The smaller the aperture, the longer the shutter speed you will need. 

First, remove the silver bayonet adapter and the tube extension.

Then, place the aperture diaphragm on top of the smaller main tube.

Next, reassemble the adapter – it can now be used as usual.
