  • It serves the role of re-collecting the light emitted from the subject to form an image on the image sensor.

  • When the number of lenses increase, the refraction angle for each lens decreases, which can reduce the spread of light. Because high resolution has smaller pixels, the core technology is to create the image without the spread of light. 

  • Unlike previous circular lenses, the D-Cut Lens is a lens that has cut the top and bottom areas, and it is advantageous in that it can minimize camera module size. 

  • It is a factor that determines the amount of light that enters the lens by combining the focal distance of the lens with the caliber. When F# is smaller, you can obtain a brighter photo. 

  • - Decenter : Distance between the center of each side of the lens
    - Concentricity : Distance between the center of the external diameter of the lens and center of the lens effective side
    - Rib Thickness : Thickness of the rib side (external side of the effective lens area)
    - SAG : Distance from the rib side of the henge (assembly base side) to the point of inflection of the lens
    - Central Thickness : Thickness of the center of the lens
    - TTL : Acronym for Total Track Length, distance from the uppermost side of the lens to the image sensor 

  • All lenses use our in-house solutions, and as our company has the necessary in-house capabilities in all areas including lens design, lens tooling, and image quality technology, our company’s lenses have less VInetting than the lenses of other companies, and low distortion lens designs are possible.  

  • It is a part that helps stabilize shaking and the focal point by moving the barrel in which the lenses are contained using a motor. The function that automatically stabilizes the focal point is AF, and the function that helps stabilize the shaking is OIS. 

  • The VCM (Voice Coil Motor) moves lenses using electric power. Based on Fleming’s left hand rule, this uses the power that is created when the current is approved under an environment with a magnetic field formed to move the lens unit. 

  • The ball guide method uses the balls within to moves the lens barrel, and the spring method uses the springs on both sides to move the lens barrel. The spring guide method has higher productivity and is more economical, whereas the ball guide method is advantageous in operational speed and accuracy. Furthermore, the ball guide method consumes less battery power with higher durability, and it can be said to be a more suitable method for the recent camera trends.
