Industrial camera selection formula ( Figure) common chip size

by:Fugen      2020-10-16
Industrial lens focal length ( fmm) Can be based on FOV ( Field of view) , WD( Working distance) And the CCD chip size calculation: the FOV view refers to the size of the object to be ingested, view based on the size of the lens distance to get object ( WD) And the lens focal length ( F) And CCD chip size of 1, the focal length of the lens, field size, working distance, optical ratio calculation is as follows: the focal length f = (WD by CCD chip size H、V) / FOV( H、V) FOV (field H、V) (= distance WD by CCD chip size H、V) / focal length f field FOV ( H、V) (= the CCD chip size H、V) WD = f (work/optical ratio distance The focal length) By the CCD chip size/FOV ( H、V) Optical ratio = (CCD chip size H、V) / FOV( H、V) 2. The size of the CCD chip table: common chip size 1. 1 inch - — Target surface size for width 12 mm * 12 mm, diagonal mm1 17 inches - — Target surface size of 12. 7 * 9 mm. 6 mm, diagonal 16 was / 3 inches - — Target surface size for wide. 8 mm * 6. 6 mm, diagonal 11 mm1/1. 8 inches - — Target surface size of 7 wide. 2 mm * 5. 4 mm, 9 mm1/2 inches diagonally - — Target surface size of 6 wide. 4 mm * 4. 8 mm, diagonal 8 mm1/3 inches - — Target surface size of width 4. 8 mm * 3 high. 6 mm, diagonal line 6 mm1/4 inches - — Target surface size of 3. 2 * 2 mm. 4 mm, diagonal 4 mm
