Customer requirements

Generally, catadioptric lenses for inspecting the outer wall can be matched with 5-megapixel, 2/3-inch cameras. However, the customer requires higher inspection accuracy and needs lenses that can be matched with higher-pixel 1-inch cameras.

Advantages of the Plan

The highest pixel match of similar competing lenses is only 5 million pixels for 2/3-inch cameras. After redesigning, the lens of this solution can be matched with 12 million or 20 million pixels of 1-inch cameras. Not only does it have a higher proportion of effective image pixels, but also a higher image contrast.
