4K Scope Comparison Form
classification：
4K Scope Model 2024
Optical Chain Theory, 4K Scope Comparison Forms, and Classification of Optical Endoscopes and Camera Systems
Optical Chain Theory:
The image transmission formula is defined as: 1000/2*×(Pixel)=Optical Resolution LP/mm2×x (Pixel)1000=Optical Resolution LP/mm
To achieve an optical resolution of 250 LP/mm, the 4K 1/8" CMOS chip cell with 2.0 um pixel size is required.
Similarly, to achieve an optical resolution of 145 LP/mm, the 1080P 1/3" CMOS chip with 3.45 um pixel size is needed.
