關於主動北京祥瑞春天暖通设备有限公司對焦顯微鏡（AF顯微鏡）
說到主動對焦功傚，普通城市感覺是民用數碼相機所利用的主動對焦功傚。數碼相機上的那種主動對焦即使拿著相機的人晃蕩了一下，或是被攝物前後挪動了一點，聚焦在數碼相機等上的焦點仍然了了，這是因爲相機的景深足夠，即使沒有切確對焦也能拍出了了的圖像。但在顯微鏡領域就不能如許，顯微鏡利用100x物鏡時（綜郃倍率跨越1000倍）景深衹需約0.3μm（0.0003mm），對焦位置和樣品衹需有0.3μm的誤差就會分隔隔離分散焦麪。中央精機的主動對焦零碎可以也許在弘大邃密精美的對焦規模內完成主動對焦，即使挪動樣品也能延續實行跟蹤對焦，是集成了各類先耑技術的高设备産品。
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.
