Aptina MT9M034 sensor/pixel size

[ecuador]

I was comparing the sensors of my cameras and I am a bit confused about the spec sheet of the MT9M034 (used in the QHY5L-II mono, ASI 120mm etc). Specifically it lists :

Optical Format: 1/3-inch

Active Array: 1280(H) x 960(V)

Imaging Area: 3.54mm(H) x 2.69mm(V)

Pixel Size: 3.75μm x 3.75μm

However, doing 1280 x 3.54μm we get a width of 4.53mm. Which would actually seems closer to the width of other 1/3" sensors, 3.54mm is much smaller.

Am I missing something? This is a mono sensor, no RGB etc to confuse things...

2 blocks sort of at the top and right hands side are reserved or used for something.

Sensor seems to really be 1412x1028 in size.

Easiest thing I think is to download the data sheet: https://www.aptina.com/products/image_sensors/mt9m034/

What you have I guess is the product flyer.

Look at page 10.

I think the imaging area figures are probably a typo.

A, yes, thank you. The product flyer data has been copied by everybody, so it was the only value I could find. So it is 4.86x3.66mm including the non-active pixels.

The flyer will be copied as it is nice and small, handing over a 55 page document is not much use.

However the data sheet shows the actual arrangement, at least it was shown and they did it nice and easy to understand - they used a picture. :grin: .

I would have thought that the picture showing the imaging and non-imaging bits would have been useful in the flyer however.

The non-active bits will be used to shift the pixel "data" into to then read them - they have to get the information out somehow.

Not easy to find that flyer anymore, so should someone else google for it, they'll probably more easily find this thread, unless they want to read trough the 50+ pages PDF...
