About autofocus microscopes (AF microscopes)
When people hear “autofocus”, many may think of the autofocus in digital cameras. Even if a photographer or a subject moves slightly, a digital camera can focus on an image.
This does not mean that the camera completely tracks the subject with the autofocus. It is just that the focus area is large, so as long as the autofocus makes some degree of adjustment, the image should net be out of focus.
However, this is not the case with a microscope.
If an objective lens of a microscope is 100x (the total magnification exceeds 1000x), the focus depth (range where the subject comes into focus) is approx. 0.3μm (0.0003mm).
This means that if the microscope and the sample are by just 0.3μm, the subject is no longer in focus.
Our autofocus is a high-technology product that allows for automatic ultramicrossopeic focusing adjustment and tracking to keep a moving sample in focus.
