CCDs 1/4" 2/3" of what?
I've seen this and never thought to ask . . . what are they an Inch fraction of? Is there a Global CCD that IS 1" square?
Grazie [ Dear Ken - Please put where you think best .. . Thanks, Grazie ] |
We were just discussing this over in the XL2 forum.
The Name designations refer back to vacuum tubes that were used in cameras before the CCD chip was introduced. So, a 1/3 inch chip is not actually 1/3 of an inch in size, but gives you the same image area as a 1/3 inch tube would have (if there were such a thing as a 1/3 inch tube). Check out this explanation on Edmund Optics site: Section 4.3 CCD Sensor Size Hope that helps. Luis |
Here's a list of various chip sizes I put together last year.
