“Rayfact UV25mm F2.8” C-mount lens release for ultraviolet cameras | Nikon Corporate News

Nikon Corporation will release the “Rayfact UV25mm F2.8” industrial C-mount lens suitable for ultraviolet cameras. Rayfact’s UV series is suitable for visual inspection of semiconductor wafers and electronic components, and is used to detect fine scratches and irregularities, and to identify materials that are difficult to separate with visible light. It is also used in areas such as combustion research and plasma research, and is expected to be used in a wide range of fields in the future.

The “Rayfact UV25mm F2.8” released this time is optimized for the Sony Semiconductor Solutions “IMX487” UV image sensor, a high-definition camera sensor with 2.74 μm square pixels, the smallest pixel size* in the industry, and has been enlarged to the edge of the image Designed for clear pictures. In addition, the clarity has been improved compared to previous products, making it possible to study a wider area with a higher resolution.
