High-resolution" lenses

When I was researching lenses for line sensors, I found that in the world of line sensors, lenses that support element sizes in the 5μm class are quite expensive as "high-resolution" compatible lenses.
On the other hand, when I looked up the element size of area cameras, I found that
2/3-inch 5-megapixel camera = 3.45μm
1/2-inch 2-megapixel camera = 4.4μm
1/2 inch 1.3 megapixel camera = 4.65μm
This means that a "higher resolution" is required.
Simply increasing the number of pixels in the camera does not provide enough optical resolution in the lens,
We have seen the phenomenon where simply increasing the number of pixels in a camera results in a lack of sharpness in an image due to a lack of optical resolution of the lens.
(If the optical resolution of the lens is insufficient, the image obtained on the element will look blurred,
(If the optical resolution of the lens is insufficient, the image obtained on the element will be blurred, and no matter how many pixels are captured by a camera with a large pixel count, no details will be visible.)
The lens of a line sensor has a large aperture, whereas an area camera may have a small C-mount,
(Considering the fact that area cameras have a small C-mount, while the lenses of line sensors have a large aperture.
"You should not touch a 5-megapixel C-mount camera.
(The large lens of the line sensor has a large aperture, whereas the area camera has a small C-mount.
