Optical Shutters
Shutter units are one of the important factors in the camera system. Today, Let’s look at the design and function in detail as following.
1st：Basic principle of shutter unit
The basic principle of the shutter unit is to open the light entering from the lens at the time of photographing to the sensor and record it. In particular, the shutter is open，the light will enter from lens and receive by image sensor，and the shutter is closed to shut off the entry of light from lens. By controlling this time, you can adjust the shutter speed and freeze or blur the movement of the subject.
The basic principle of the shutter unit is the basis of photography technology. Understanding this principle helps to improve the quality of photography.
2nd：Internal structure of shutter unit
The internal structure of the shutter unit consists of advanced engineering and precise parts. This is an essential element for the shutter unit to work at an accurate shutter speed.
Internal structures have different designs depending on different models and manufacturers, but common elements include coils, springs, and shutter blades. These elements interlock to keep the shutter unit open and close for precise timing.
3rd: Mechanism of high-speed shutters
High speed shutter is essential to capture instant moments. Therefore, the mechanism of high-speed shutter is required to be precise and fast. A high speed shutter has the ability to realize shutter speed in milliseconds and to stop the movement of the subject.
The operation mechanism of the high speed shutter is realized by the quick opening and closing of the shutter blade and the data transfer rate to the sensor. This makes it possible to capture the instantaneous moment, and to exhibit excellent performance in sports photography and moving objects.
