Lens optical axis eccentricity measurement + alignment VCM optical axis coaxial processing machine

The lens optical axis is measured, and the optical axis is coaxially aligned with the rotation axis while performing core processing on the flange reference surface and outer diameter of the cell (housing). Since the cell lens is processed while aligning the optical axis, the optical axis of the lens and the axis of the cell become coaxial. In the ATS200, the lens cell arranged with a 4-axis alignment-capable collet chuck (XYθ) can achieve positioning within 0.1μm before and after energization, allowing for processing with minimal alignment time after measurement, resulting in a flatness of less than 0.2μm and a planarity of about 0.01μm after processing. Eccentricity measurement, outer diameter measurement, and lens height measurement are also included as standard functions, and selections can be made from the lineup based on the target diameter and other factors.

basic information

ATS100: A compact type designed for cell lens processing with a diameter of 100 mm and a weight of up to 3 kg. ATS200: Designed for cell lens processing with a diameter of 200 mm and a weight of up to 5 kg. ATS400: Designed for cell lens processing with a large diameter of 400 mm and a weight of up to 30 kg. 【Lens Cell Optical Axis Alignment Processing Service】 We also offer processing services using the ATS equipment set up as a demonstration machine. If customers provide samples of lenses fixed in cells, we will process and remove the eccentricity of the cell based on the optical axis. In addition to removing eccentricity, it is possible to specify dimensions (inter-surface spacing) from the top and bottom surfaces of the lens to the flange surface, as well as the outer diameter of the cell, in micrometer units.
