That's why InGaAs is much better both for lower dark current and higher QE.

To be fair, I set the TEC to 25C for the "room temperature image" (see the TriWave Gallery page) to stabilize the temperature. For any kind of dynamic range, yes cooling is necessary...but 'an absolute must'.....well, have a look at the image.<br />At best, I think a one stage TEC should be used but would recommend against no cooling at all. Significant packaging cost reduction going from a 4 stage to 1 stage TEC!<br />We have seen no issues with the microlenses at -80CSeth Pappasnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-43219927762859827352015-08-21T15:09:47.699+03:002015-08-21T15:09:47.699+03:00I quickly calculated the dark current for 33 ms at...I quickly calculated the dark current for 33 ms at +25 deg.C, and that gives over 20k electrons of dark current. That is not a little bit .... This is almost full well at room temperature.<br />Of course you can correct for the average dark current and you can correct for the dark fixed pattern noise, but unfortunately you can not correct for the dark shot noise that comes together with this large dark current. So cooling will be an absolute must !Albert Theuwissennoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-12989903143443676702015-08-21T13:28:09.358+03:002015-08-21T13:28:09.358+03:00Just to add this in, there are sample images withi...Just to add this in, there are sample images within the white paper, and just to clarify their QE results are normalised to the maximum, hence I had a quick double take on seeing 100% QE...<br /><br />Very nice.
