說到自動對焦功能，一般都會認為是民用數碼相機所使用的自動對焦功能。數碼相機上的那種自動對焦即使拿著相機的人晃動了一下，或是被攝物前后移動了一點，聚焦在數碼相機等上的焦點仍然清晰，這是因為相機的景深足夠，即使沒有準確對焦也能拍出清晰的圖像。但在顯微鏡領域就不能這樣，顯微鏡使用100x物鏡時（綜合倍率超過1000倍）景深只有約0.3μm（0.0003mm），對焦位置和樣品只要有0.3μm的偏差就會離開焦面。中央精機的自動對焦系統能夠在微小精密的對焦范圍內實現自動對焦，即使移動樣品也能持續實施跟蹤對焦，是集成了各種先端技術的高科技產品。
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.
