e2v Sapphire Videos

e2v publishes Youtube videos of its 1.3MP, 2MP and WVGA sensors from Sapphire family:

  1. I have experience with these sensors and the impression bad. The sensors are very noisy (7e rolling, 21e global). Real sensitivity, unlike that which the manufacturer claims is very low (even at full moon you can see a very bad, despite the fact that we are TEC cooled sensor). The price of the sensors is very high, at the same time he clearly all the parameters will lose IMX252. Apparently e2v decided to take advantage of the temporary problems Sony to regain lost ground. Waste of money for filming these clips! :) At the moment, the kings of the market that Sony and Gpixel

  2. What is the ball park price for such sensor?
    I don't think Sony ones are cheaper?

    1. They are usually well placed on price versus other similar sensors

  3. E2v makes the best sensors

  4. Sony IMX265 (simplified version IMX252) is 3-5% lower than EV76C560. You can see the results of the comparison of Point Gray. EV76C560/570/660/661 was interesting when they first came out, (6 years ago, I heard from IDS the phrase "killer CCD") and now this expensive junk. The real "killer CCD" steel sensors Sony Pregius.
    On account of the allegations, "E2v makes the best sensors in the business market this is not true, and in the science of astronomy and space TEMPORARILY. :)
    "A large closet loudly falls", remember Kodak, when the CMOSIS. Now there Gpixel, which in 2-3 years will change the market.

    1. Those Ruby and Sapphire sensors were viable for a moment in amateur astrophotography. They were faster/cheaper than similar Sony CCD based cameras, and better than for example IMX035 also available at that time. But now Sony CMOS wins all the way with lower read noise and multiple shape and sizes. The e2v sensors had to be run in rolling shutter mode as global was to noisy - but in the end it still works somewhat ok.

  5. I assure you that IMX035 cost 7 times cheaper than EV76C560, and are the difference in cost of cameras only pricing of camera manufacturers.
    In addition, in the articles they filmed in very bright astronomical objects (Sun, Moon, etc.) that does not give a complete picture of the capabilities of the sensor in bright light all the sensors off relatively well. :)
    The only indisputable advantage of the e2v CMOS sensors is the ability to work with short exposures 16 microseconds. Even CMOSIS could not provide on their fast sensors such short exposure

    1. Could you please explain why shorter exposure is an advantage in astronomy app? Isn't it always longer exposure + low DC?

    2. Such a short exposure, the sensor in machine vision or traffic control, when the subject is moving too quickly. Of course for astronomy such a short exposure is not needed if you are not meteorites and comets shoot. Your exposure will be relevant in active imaging, which announced in EV76C570, but given the low sensitivity of the sensor is not clear where to apply it. All systems are active imaging with Image intensifier and CMOS e2v in this segment can not compete even with a Image Intensifier Gen1.
