Sony Presents New Generation Global Shutter Sensors with 3.45um Pixel

Sony announces 5.07MP 2/3-inch IMX250LLR/LQR and 3.2MP 1/1.8-inch IMX252LLR/LQR sensors featuring a new generation global shutter pixel. Sony says that the new 3.45um pixels are industry's smallest global shutter pixels for industrial applications. The pixels feature improved sensitivity, 1.1 times over the company's previous generation of 5.86 µm pixels. In addition, EXview HAD CCD technology is said to increases sensitivity in NIR (see the bigger 800 x 670 pictures on Sony site):


The sensors are fairly fast, slightly faster than the previous generation IMX174:


Sony also publishes a Youtube video showing a global shutter advantage:

    Does anyone know if this are stacked sensors? e.g. the "photodiode layer" being a seperate die bonded on top of the "logic layer"? (Because I think to be able to create such small global shutter pixels you need to move functional units away from the "photodiode layer"). If they were stacked, what functional units would still be in the "photodiode layer"? And how many pixels would require a connection between the layers?

      it is exmor, which means it is front.

      I guess it is not a stacked sensor, because stacked sensor is BSI and BSI global shutter is challenging to design even for Sony.

      The website only says "Exmor", so it is not stacked (Exmor RS) nor BSI (Exmor R).

    Omnivision offers a 3um global shutter pixel for over a year (OV7251).

      Sony says "industry's smallest global shutter pixels for industrial applications." Omnivision's one is for consumer apps, although there is just a wording difference.

      I think the significant point is that this is the smallest global shutter pixel for a high definition (or more) CMOS sensor.

      Anyone has experience with this OV GS sensor please?

    For a second (from the Youtube preview) it looked like there were rolling shutter artifacts but in a different direction. On watching the video I see its because they used a wide angle lens. They should have used a telephoto or the industry standard fan shot.

    Having a small global shutter is not too difficult, the trouble is getting a decent performance.
    OVT 3.0um didn't gave any pixel performance data.
    I would be interesting to see full well, noise, so dynamic range and QE.

    So giving only the pixel size is just an useless data without more info.

    Does it exist already some data on the Sony 3.45um?
    The 5.86um was tested at 73dB, so far.

    You can get these datas easily from Omnivision.
    Below some specs related to the OV7251 rev.1G (rev.1F is currently available):
    FWC: 8000e- (7000e- for rev. 1F)
    Shutter Eff.: 99.9% visible light, >99.76% NIR (950nm)
    SNR max: 39dB
    Dynamic range: 69.9dB @ 16X, 64.3dB @ 1X
    QE peak: 60%
    QE: IR (850nm): 30% (rev 1 G)
    Dark current: 500e-/s

    According to EMVA1288 we measured the 3.45µ pixel and got:
    57% QE @ 533nm
    2.1 e_ dark noise
    DSNU of 0.97e-
    SNR of 40 dB
    PRNU of 0.549%
    LE of 0.11%
    fullwell of 9922 e-
    sensitivity of 2.8e-
    Dynamic range of 71.1 dB
    It's a FSI CMOS sensor.

    hi all

    does anyone have a rough physical size of IMX252?

    thx

      Sony doesn't list this on the brief data sheet but here is a picture - http://www.framos.com/products/en/imx252lx-17093.html

    This looks more like a generic picture then anything else

    anyone know the unit price estimation of IMX252LLR at quantity say 20,000?
