Teledyne-DALSA Announces 60MP Medium-Format CCD

Marketwire: Teledyne-DALSA's new 60MP FTF9168 CCD is said to offer the highest resolution available in the industry today within a 645 optical format that can be imaged using commercially available lenses. Available in both RGB-Bayer color and monochrome versions, the FTF9168 CCDs are targeting the resolution-demanding applications like fabric and artwork reproduction, document scanning and aerial photogrammetry. The sensor is based on 6um pixels and has the maximum frame rate of 1.4fps.

FTF9168 features:

  • Very large optical format (54 x 40 mm2)
  • 60 million active pixels (8956H x 6708V)
  • >95% fill factor
  • Micro lenses with wide angular response
  • High sensitivity & dynamic range (>70dB)
  • Data rate up to 25 MHz per output (4 outputs)

"With our internal wafer foundry, we can control the entire process from design to delivery, offering both the ultimate in performance tuning and security of supply," said Jelle de Jong, Director of Marketing and Sales at Teledyne DALSA in Eindhoven. "The FTF9168 contributes to our continuing history of excellence and is the highest-resolution large optical format sensor available on the market today."


DALSA publishes a complete datasheet simultaneously with the announcement - quite a rare occurrence in the industry. The QE graphs are among the officially presented data:


With the new sensor, the large format CCD lineup from DALSA spans from 22MP to 60MP:

  1. This sensor may be very good, and high megapixel, but it is not the "highest resolution available within a 645 optical format".
    The sensor present in the Phase One IQ180 digital back is the same 645 size, but with 80 Megapixel.

    1. That 80MP sensor is also by Teledyne-DALSA. They didn't forget that they make it! The key thing about this press release is their precise use of the word "available". Some of their medium format sensors (40MP, another 60MP, and 80MP) are not "available" to everyone; only to the Phase One/Mamiya-Leaf conglomerate. They don't even publish datasheets for those sensors (I've repeatedly asked for them and been ignored!).
      So what makes this new 60MP different is that is available to all 3rd party developers, and the datasheet is public.

  2. Why is the peak QE so extremely low?
    They've got micro-lenses and high fill factor. Peak QE of 60% should be easily attainable.

    Also, why the QE so low for short wavelengths, and increasing towards longer wavelengths? Is this BSI? If so, you think they would advertise that (unless they are embarrassed by the low QE).

  3. I'll guess it is the Philips - now DALSA - CCD T-gate so there is some partial poly obstruction which predominantly affects blue.

  4. Are they using photogates or pinned photodiodes for light sensing?. Photogates could explain the low blue QE (and vertical anti-blooming could explain loss of QE in part of green, and Red)?

  5. OK, forget the T-gate. Look here:

    1. I have a question reading the references.
      Photons seems to enter under the CCDs when they are transferring charges.
      Can we use it monitoring the (1.4fps) image on a backside LCD?
      Or can we just see the images separated by mechanical shutters?

    2. I think a mechanical shutter is required for this full frame CCD. Interline transfer, frame-transfer or combined FIT architectures are required for electronic shutter with CCDs. Even with these architectures, some light-generated electrons do get into the transferred signal. This is known as smear.

      I guess if the economics allowed it, a CMOS APS could do this job better than a CCD. But this low volume application is based on decades of nice incremental progress at DALSA (Philips) on large area stitched CCDs.

    3. I'm so glad receiving an answer from you, Dr. Fossum.
      A CIS can take images continuosly, so I wondered the question I asked.
      In the answer, the second half was more than I expected.
      Thanks a lot!

    4. Most CIS is rolling shutter. ILT/FT/FIT are all global-shutter architectures. But global shutter CIS at 6 um pixel size is not so difficult. Again, you need a customer or application that would be able to justify such development cost and that is as important as the choice of technology.

  6. You know the price of this chip?
