The images, the noise and the sensitivity of a camera with the 1310 sensor were impressive. At that time.<br />Today since the IMX174 there are new rules. I can say, the big advantage is the sensivity in the high NIR. 1064 or 1100nm and above.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-81453672106031767902017-09-26T10:47:24.727+03:002017-09-26T10:47:24.727+03:00Invisage has 40-45% QE at 940nm, but its spectral ...Invisage has 40-45% QE at 940nm, but its spectral response is different having a peak in IR:<br /><br />http://www.imagesensors.org/Past%20Workshops/2017%20Workshop/2017%20Papers/R53.pdfVladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-68769610498511908402017-09-26T10:41:37.412+03:002017-09-26T10:41:37.412+03:00Though I'm happy to see this progress, I have ...Though I'm happy to see this progress, I have problem to take a company seriously that claims "extremely low read noise", "extremely high sensitivity", "sensitivity enhancements as high as 10x today’s sensor solutions", without specifying any numbers or graphs to support that claim.<br />Also, the night vision field test video looks nice but it is unclear which cameras are used for the comparisons.<br /><br />Jochem Herrmannhttps://www.blogger.com/profile/16549019789626919232noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-41795595985257061612017-09-26T02:05:37.914+03:002017-09-26T02:05:37.914+03:00How does it compare to Invisage in terms of NIR/IR...How does it compare to Invisage in terms of NIR/IR sensitivity?

There is a cookie brand in the US that advertises that their cookies are baked by little elves in a hollow tree. (OK, I know ESPROS has now moved on to TSMC for some devices, perhaps all.) Anyway, all of these folks pushing the limits of silicon image sensors deserve a lot of credit.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89802909527485479112017-09-24T09:07:51.713+03:002017-09-24T09:07:51.713+03:00This week at AutoSens, ESPROS reported a QE = 70 %...This week at AutoSens, ESPROS reported a QE = 70 % at 905 nm wavelength.

It is not mentioned which CMOS sensor they use for comparison AND both graphs are normalized. Basically it doesn't say anything about the comparison between the two technologies. Only the shape of the curves can be compared. <br />Also your statement about the dark current I do not subscribe. The text in the blog says : a COOLED camera. So comparison of the dark current without numbers and temperatures indicated is very dangerous.Albert Theuwissen - Harvest Imagingnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-51138808231774603522017-09-22T17:46:42.248+03:002017-09-22T17:46:42.248+03:00Congratulations to SiOnyx on getting traction in J...Congratulations to SiOnyx on getting traction in Japan. On the other hand, I wouldn't call it a "radically" different technology. It does improve red/NIR absorption in silicon without creating an optical cavity (a tuned increase) or add significantly to dark current. I can't say much more except to give it thumbs up for certain applications.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.com
