Optical lens system has various motors for zoom, iris and VC(Vibration Compensation).
Tamron constitutes an elaborated lens system, in accordance with required function and quality, by selecting an optimal motor among ultrasonic motor(ring type/standing wave type), brushless motor, stepping motor, voice coil motor and by developing actuator control system depending on each motor. Tamron’s strength is the system design with Actuator, Control Circuit and Software thoroughly by itself to integrate motor and optical system.
Tamron aim to solve many challenges in new applications and fields by utilizing the technology of quietness, high-speed, high-durability and high-torque cultivated throughout optical lens system.
There are three types for compensating the camera-shake and Tamron’s Vibration Compensation system is based on optical technology consisting of a three-axis voice coil motor, a position sensing hall sensor and gyro-sensor for detecting angular vibration.
Compensating the vibration can not be realized with a motor independently. Lens capable of having optical compensation is executed with feedback control responding to an angular velocity from gyro sensor and the imaging performance is maintaining while shooting.
Tamron design thoroughly the three developments “VC mechanism (ACT) development including optical design”, “Sensor signal processing circuit technology”, and “Control software development” and realize a fine drive and stopping accuracy in micron order.
With a unique AI algorithm, Tamron engage in a seamless Vibration Compensation corresponding to various shooting conditions and kinds of vibration. Moreover, a variable optical axis (beam bending) is possible by utilizing VC technology.
From now on, utilizing the VC technology is in our view to be widely used such as wearable devices, a long- distance monitoring devices and a moving equipment such as robot.
