How to calculate Sensor Pixel Pitch?

I need to compute the “Sensor Pixel Pitch (in mm/px)” for some calculation. I have the following data available from the manufacturer:

Resolution: 1920x1200
Sensor Type: 2/3” CMOS
Pixel size: 4.8 x 4.8 µm


So, far I just found that the sensor pixel pitch the distance between one pixel to next but I do not know how can I compute that value from the above data.

• Did you read the last line there? 4.8 µm = 0.0048 mm... Jun 24, 2019 at 14:00
• @twalberg: That's pixel size but what I found on other articles is that sensor pixel pitch = distance between two pixels...Are pixel size and pixel pitch the same thing?

• For verification - note that calculating the diagonal of the sensor with 1920x1200 pixels of 0.0048mm gives 10.8679mm, which is pretty close to the nominal size of that sensor... Jun 24, 2019 at 14:28
• I agree with twalberg — it's just a question of precision, which comes down to needing to know why you need this number. Jun 24, 2019 at 14:31
• I'm voting to close this question because OP states in comment "I don't have the exact sensor size" -- well, then, this question can't be answered unless you specify that a "meh, close enough" answer will work. Jun 24, 2019 at 16:20

You can't from this information, because "pixel pitch" is: sensor length divided by number of pixels along that dimension. You don't have sensor size — the 2/3" designation is generally around 11mm diagonal, but can vary in specifics.

It's possible that "pixel size" in this spec also means "pixel pitch", but it's also possible that that's been measured in a different way. The given number lines up reasonably well (given a 1920×1200 sensor, that'd be a diagonal of about 10.9mm).

Depending on your needs, that might be close enough. Do you have the exact dimensions of the imaging area from which the 1920×1200 readout is produced? If you need more precision, you'll need that.
