In the lens processing, in order to manufacture a lens with the required performance, various conditions need to be adjusted by selecting the machine used for manufacturing and adjusting the polishing time according to the magnitude of curvature and the characteristics of the material.
For example, high-pixilation and high-definition are yearly advanced in CMOS image sensor used in cameras and a lens surface-roughness, unevenness or waviness negatively effects the lens imaging performance.
To enable a highly accurate lens, Tamron reflect a simulation result to a processing accuracy from the optical designing stage.
Tamron’s lens processing technology is covering a wide range, multiple lens bonding with curved surfaces, processing with plane lens and prism lens, and prism lens bonding with each other. From now on, as a new usage, optical lens is expected to be used with laser and to be required a complicated irregular shape or prism shape integrating various technologies.
To produce multifarious lenses required in the future, Tamron is newly developing and improving the processing technology and handing down its established expertise by cooperating the lens processing know-how and the optical development technology.
Glass molded lenses are made by heating the glass material at an high temperature and pressing it with an elaborate mold made in nanometer units. Although the production efficiency is high, it is molded in a thin-walled shape. It can sometimes crack and requires an advanced manufacturing process.
Tamron has realized an ultra-thin, small-diameter aspherical glass molded lens with a thickness of 0.1 mm, which is equivalent to copy paper. It can be expected to be used in optical systems such as wearable devices, robot eyes, and minimally invasive surgical cameras.
Tamron is evolving its lens processing technology in order to create lenses that can meet the ever-increasing demands for smaller equipment and higher resolution.
