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!). <br />So what makes this new 60MP different is that is available to all 3rd party developers, and the datasheet is public.<br />Ray Butlernoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-74303465703844307592012-09-12T17:55:57.138+03:002012-09-12T17:55:57.138+03:00Most CIS is rolling shutter.

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.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-45086409354912593882012-09-12T16:53:55.647+03:002012-09-12T16:53:55.647+03:00I'm so glad receiving an answer from you, Dr. ...I'm so glad receiving an answer from you, Dr. Fossum.<br />A CIS can take images continuosly, so I wondered the question I asked.<br />In the answer, the second half was more than I expected.<br />Thanks a lot!<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-37232030482478253892012-09-12T13:30:11.124+03:002012-09-12T13:30:11.124+03:00I think a mechanical shutter is required for this ...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. <br /><br />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.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-33621292114191200212012-09-12T04:31:58.495+03:002012-09-12T04:31:58.495+03:00I have a question reading the references.

Peak QE of 60% should be easily attainable.<br /><br />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).<br /><br />-DPAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-87198502460489595942012-09-11T17:10:37.117+03:002012-09-11T17:10:37.117+03:00This sensor may be very good, and high megapixel, ...This sensor may be very good, and high megapixel, but it is not the "highest resolution available within a 645 optical format".<br />The sensor present in the Phase One IQ180 digital back is the same 645 size, but with 80 Megapixel.Anonymousnoreply@blogger.com
