Types of autofocus solutions

Laser autofocus microscope

In-line: Real-time sensing and focus adjustment of small undulations on the sample surface is achieved through precise positioning and fast feedback of the laser beam.

(Single-head) APO Laser AF Microscope-Motor: motor-driven for autofocus, with high focusing accuracy and speed.

(Single-head) APO Laser AF Microscope - Piezoelectric: utilises the piezoelectric effect to achieve fast focusing, with higher focusing speed and accuracy, usually used where high precision focusing is required.

Spectral autofocus microscope

APO Spectral Autofocus Microscope: Combines spectral analysis techniques for more sophisticated focusing and imaging needs.

Other autofocus solutions

These include ranging methods (infrared, ultrasonic, triangulation), rotating diaphragm out-of-focus detection, video signal analysis, focus detection (contrast, split image, phase detection), and time-of-flight and masked pixel phase detection. Each of these methods has applications in modern autofocus systems such as cameras and microscopes.
