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.
特点 Features
优秀的跟踪性能
即使样品表面起伏或是倾斜也能实现跟踪对焦。
Excellent tracking performance.
Two-line sensor method for high-speed tracking of undulations and slopes can maintain continuous focus.
世界唯一的线阵传感器方式
世界上唯一使用线阵传感器(one-dimensional image sensors)的自动对焦显微镜系统
Word’s only line-sensor autofocus system.
The word’s only autofocus system that utilizes line sensors (one-dimensional image sensors).
独有的高性能
不仅适用于高反射率的金属表面，也适用于低反射率的纸张、滤纸、玻璃、透明塑料等材质；能够发挥其他类型自动对焦系统无法做到的高性能，是同时拥有高性能和高适用性的自动对焦系统。
Word’s leading focusing performance than ever.
