Digital telescope lens system structure-Alice factory

October 22, 2021

From the front of the lens, the structure of the photographic lens of a digital camera is as follows:

The lens protection glass, lens components, optical low-pass filter, infrared cut filter, image sensor, and shutter are placed in the middle or in front of the lens assembly, and most of them are used in conjunction with the aperture.

The center resolution and edge resolution of the lens: the center resolution and edge resolution of the lens are the imaging devices that convert optical signals into electrical signals. In a certain area, the more pixels there are, the optical signals are converted into electrical signals. There are more pixel units.

However, the pixel interval has a limit, that is, the pixel size cannot be too small. Otherwise, the yield of production will be greatly reduced, resulting in a substantial increase in production costs.

Generally, the pixel interval is less than 5μm. For a 1/4-inch element, its length and width are 3.6mm, and the number of pixels is 800(H)×510(V).

Optically, black and white lines are used as line pairs, and the resolution is based on how many line pairs can be separated in a length of 1 mm.

When designing the lens, in order to satisfy the pixel interval below 5μm, the resolution of the lens must be above 100 line pairs/mm.

But for the lens, since the resolution of the edge of the picture is only 50%~70% of the center resolution, in order to ensure that the full screen is 100 line pairs/mm, when designing the lens, the resolution of the middle part should be 150~200 lines. Yes/mm.

As the evaluation of digital camera lenses is getting more and more attention, from the 2010s to the 1920s, some models were separately indicated in the manuals.
