エフケー光学研究所 List of Products and Services

The FK Optical Research Institute's foreign matter inspection device is a wavelength-selective inspection device that switches to the optimal light (wavelength) for inspection based on the sample being inspected. It can uniformly illuminate at any wavelength. The optical design sufficiently suppresses stray light noise components for the inspection imaging sensor. Additionally, we offer a rich lineup that can be optimized for your production line configuration. 1. It performs inspections on film-like sheets and substrates transported by roll-to-roll or conveyor systems. 2. It inspects for fine pinhole defects and foreign matter adhered to the surface. 3. Depending on the material after film coating, it can also detect defects such as streaks in the coating application. *For more details, please refer to the PDF materials or feel free to contact us.

It can uniformly illuminate at any wavelength. The optical design sufficiently suppresses stray light noise components for the inspection imaging sensor. Additionally, we offer a rich lineup that can be optimized for your production line configuration. 1. Area type that inspects glass substrates placed on the inspection stage using multiple area sensors. 2. Scan type that inspects glass substrates placed on the inspection stage by moving the foreign matter inspection machine to scan. 3. Conveyor type that inspects foreign matter on the surface of glass substrates being transported on a conveyor. 4. Backside foreign matter inspection type that inspects foreign matter on the underside of glass substrates being transported on a conveyor. *For more details, please refer to the PDF materials or feel free to contact us.

The "MD-60AA Series" is an assembly device that automates high-precision multi-axis focusing, tilting, alignment, and adhesion, enabling camera module correction. It is suitable for mass production of camera modules for a wide variety of applications, covering a maximum FOV (Field of View) of 180°. By performing high-precision multi-axis adjustments based on MTF calculation results, it achieves high image quality and supports the assembly of image modules for diverse applications. 【Features】 ■ FOV 165° (MAX 180°) - Optimal image quality is achieved through alignment across the full FOV (entire field of view). ■ Adjustment of image area - Easy modification of the test area with an adjustable collimator. ■ Adaptation to different object distances - Adjusted for infinity focus. - BFLOffset is adjusted according to the object distance. ■ Accuracy and efficiency - Alignment is performed by measuring image quality across the entire FOV to obtain the optimal image plane. *For more details, please refer to the PDF document or feel free to contact us.
